The Big Spit

By

Friday, February 10th, 2012

I was supposed to go to Florida for a couple of months this winter. Toss my binoculars, my bird guides, my bathing suit, my golf clubs and my dog into the camper and head south. Ah, warmth.

They call Florida a peninsula, but it’s just a giant sandbar. A friend of mine calls it “The Big Spit”. I was really looking forward to being roasted brown. Well, those plans went out the window.

Then I got an invitation from my long-time friend Charlie Rattigan to join him at the Space Coast Birding and Nature Festival. I knew nothing about the festival, but Titusville, Florida had to be warmer than Winnipeg. And it was in an area where I could finally, maybe, find the Florida Scrub-Jay, a bird that had eluded me on three previous trips to The Sunshine State. Maybe the Red-cockaded Woodpecker and the Brown-headed Nuthatch too.

Getting a plane ticket at the very last minute means one thing: bad itinerary. I had to get up at 4:00 am, fly to Chicago, wait there, fly to Cleveland, wait there, then fly to Orlando. Wait there too — for Charlie to arrive. ARRRRGH! Fourteen hours sitting on airline seats and in noisy terminals!

Only one week in Florida instead of two months: I’d better make the most of it.

We got to Titusville a day before the festival began and decided to do some preliminary birding on our own. Using the Audubon Birds app with its “Find Birds with eBird” connection on Charlie’s iPhone, we quickly found out where Florida Scrub-jays had recently been spotted. Of the numerous sightings, Cape Canaveral National Seashore seemed like the perfect choice; it was not only close but shared a border with Merritt Island National Wildlife Refuge.

When we got to the fee station on Merritt Island, we asked the ranger on duty where the Scrub-jays were. An affable, talkative guy, he told us to park the car and walk behind the ranger station. We couldn’t believe it. They could be right there!

Then again, the curse of the mythical Florida Scrub-Jay could still be operational. I’d missed a sure thing before; I could be unlucky again.

Before we began walking around, we checked the app for the songs and calls of the jay, not as noisy and insistent as a Blue Jay. The Florida Scrub-Jay is quieter, a more modest “shreep.”

Right away we saw a jay-sized grayish bird scooting through the bushes. Could we be so lucky as to see a Scrub Jay this quickly? Nope. It was a Northern Mockingbird (very plentiful in Florida).

Was that a “shreep” we heard on the other side of the bushes? Was that the mockingbird mocking us, imitating the jay?

We cut though the bushes and got to an opening where the railroad tracks separated the refuge from the Kennedy Space Center. We’d been warned not to go past the tracks. For a second I thought to myself: am I willing to be clapped in jail for a lifer? Will I have to cross the tracks to find the elusive Florida Scrub-Jay?

In the time it took to ask and answer my own question, it became irrelevant. A Scrub-jay appeared as if out of nowhere, flying across the tracks from the Space Center property and perched in a small tree next to the tracks. Then suddenly another, and another, and another. Four Scrub-Jays. Three hopping on the tracks coming ever closer. We hoisted our binoculars and took them in. Soon we didn’t really need to. They were close enough to see clearly with the naked eye. These are lovely birds. A blue that reminds me of the color of a Mountain Bluebird with a white throat and a necklace of blue.

These Scrub-jays were curious and fearless like their cousins the Gray Jays, the “Whiskey Jacks.” The boldest one, with four leg bands, bounced along the railroad ties and came within a foot of my boots. The three others, without bands, got within six feet or so, but no closer. The jays stayed until we had imprinted them indelibly in our minds. What a great way to get a lifer!

On our way out, we thanked the park ranger. He asked if we were interested in owls too. When we said yes, he told us to stop down the road and look in an open field surrounded by a fence.

There on a fifty foot high pole was an Osprey nest. In the nest was a Great Horned Owl. Clearly, a lazy but feisty owl.

We poked around the island some more. Man, there are a lot of vultures in Florida! Has the economic depression attracted them in such numbers, or is it always like this? Hardly a minute passed without us seeing either a Black or a Turkey Vulture, often dozens at a time. Soaring, teetering, swooping and looking for carrion. Eerie!

And Coots. Coots everywhere! The ponds and lagoons of Merritt Island are full of coots. We saw hundreds and hundreds at a time. And lovely views of Snow and Great egrets with an occasional Tricolored heron in the mix of birds.

Our daily list had reached thirty birds in less than three hours when we decided to head out. We’d seen some great birds: a Bald Eagle (always a thrill), Northern Cardinals, Pine warblers, Boat-tailed Grackles (better vocalizations than their Common cousins), Red-bellied woodpeckers (pretty common), Eurasian Collared-Doves, and White Ibises, to mention just a few.

On our way off the island we decided to stop at a beach on the north side of the road just before the bridge. We’d seen some gulls and waders along the shore from a distance.

The gulls included: Ring-billed, Bonaparte’s, Laughing, Great Black-backed. There were some interesting terns. Forster’s (always a special treat) and side-by-side a Caspian and a Royal Tern, offering a great opportunity to note the subtle differences. White crown and yellow-orange bill on the Royals, black skullcap and red-orange bill on the Caspian.

Among the gulls and terns, a special bird for me, also turned out to be a lifer. Black skimmers, close to 100 birds resting about 10 yards offshore on land that had not been covered by the tide. One took off and flew closer. With its lower mandible skimming the smooth surface of the lagoon, it was unmistakable – even for someone who has never seen one before.

We then turned our attention to the shorebirds. Shorebirds are a challenging species for me and many people. It’s often impossible to distinguish one from another, particularly when they are dressed in their winter plumage. It can be frustrating. Paying attention to behaviour near the water’s edge will provide the observer with ID clues.

There were Ruddy Turnstones, turning stones: always fun to see, sanderlings behaving like wind up toys, and dunlins actively feeding.

It was a remarkable morning of birding – sharing the experience of seeing two life birds with my friend as well as the enjoyment and challenge of finding and identifying birds in this still wild area shared with scrub-jays, rockets, and astronauts.

A Bad Winter for Rodents

It’s been a very mild and almost snow-free winter in Manitoba so far this year. Good news for us. Bad news for mice and shrews and voles. They rely on a thick blanket of snow to survive the winter.

A couple of years ago as I watched a Great Grey Owl along a road in the boreal forest east of Winnipeg, it suddenly left its perch on a hydro pole, swooped over the road-edge, and plunged, talons-first, into the thick snow. It immediately extricated itself and flew back with a small, squirming rodent.

Wow! I wondered. How’d it do that? I knew that owls had great hearing. But the snow was at least a foot thick. That, it seemed to me, was like me hearing a pin drop a block from my house.

And what was a rodent doing in a snow-bank? I thought they hibernated all winter or found a warm place like my basement to hang out.

That’s when I first heard about pukak.

Pukak is that small space under the snow and above the ground that forms when the snow piles up more than a foot or so and when the earth’s warmth melts the bottom layer to form passageways for insects, rodents and tiny mammals.

Mice and shrews and voles use these passageways to seek out seeds and grasses and bugs left over from the summer and fall. At irregular intervals vents form to allow gasses to escape. Owls listen to the tiny noises that emanate from these vents.

With barely three inches of snow on the ground this year, pukak hasn’t yet formed. That means the rodents can’t leave their winter hideouts. They don’t have to worry about owl attacks, but they are in danger of starving. The thicker the snow, the better their chances of surviving the cold.

The Sounds of Snow

Dog Tracks

Dog Tracks by David Tyler

We often associate snow with silence, except when there’s a fierce snowstorm or blizzard. Then the wind seems to fill our heads with noise, a ferocious kind of white noise.
Gently falling snow can dampen the soundscape. That’s because a fresh layer of snow can absorb sound. Air gets trapped between the grounded snowflakes and minimizes vibrations. It’s the same principal as holes in ceiling tiles. Tiny holes in the snow mean sound waves get impeded, and the world seems a softer, quieter place.

When snow settles or melts and refreezes, the world suddenly gets noisy again. The holes between flakes disappear, and sound waves accelerate. That’s why sound carries so well in winter. You can hear a wolf howl or a dog barking from what seems like miles away.

Walking through the snow in Winnipeg is much noisier than walking was in my hometown of Rochester, NY. It makes a creaking sound – like the rail of a rocking chair on a loose floorboard. Rrrrutch. Rrrrutch.

Rochester has very temperate winters. Snow quickly turns to slush. You get a squishy sound. Snow above the temperature of 15 degrees Fahrenheit (minus 10 Celsius) will not squeak. The pressure of your boots partially melts the snow underneath it; you’re essentially walking on a thin layer of water.

In Winnipeg where it’s usually colder than minus 10 Celsius for much of the winter (November 1st to April 1st), the pressure of your boots and body weight crushes the ice crystals and makes a distinctive, rrrutching sound.

When Foley artists add the sounds of footsteps in the snow during the editing of a Winnipeg movie, they usually bring along an unopened box of baking soda. Press your thumb hard into the side of the baking soda box, and you get the sound of a footstep through the snow in Winnipeg. Try it!

The Christmas Bird Count

It’s called “Citizen Science”, and the Christmas Bird Count is often cited as an important contribution to the understanding of winter bird populations. But for most participants the sleuthing and the camaraderie outweigh the science.

I’ve been a Zone Captain (Zone 7 out of 12 zones) for the Christmas Bird Count in Winnipeg for over twenty years. I’ve recruited my team for this year, and we’re excited to see if we can outdo our efforts of last year and find something rare and unusual to boot.

Our count this year is on Sunday, December 18. It’s one of twenty or so in Manitoba and more than 2000 across Canada. More than a dozen other countries play host to Christmas counts besides Canada and the US; among them are Mexico, Guam, Costa Rica, Ecuador and the Bahamas. I once helped on the downtown Honolulu count, and I’m looking forward to helping in other tropical areas in the future.

Winnipeg’s count day can be cold and blustery, but even on a good day we usually don’t get many birds or species. My area usually gets between 15 and 20 species. Overall for Winnipeg we get between 40 and 50 species. The numbers fluctuate, and that’s part of the science. Huge databases have been compiled from the over 100 years of the counts.

The fun comes in finding rarities, the birds that aren’t supposed to be here. We’re always good for several each count. A wayward cardinal or Townsend’s Solitaire; some Mourning Doves that think they can outlast the winter; an oriole tempted to stick around with a feeder full of mealworms. We’re always hoping that someone at the tally dinner will surprise us with something we’ve never had before.

Most counts are organized by local Audubon societies and naturalist groups. You can go out in the field or sit at your feeder and count. Find out who’s running it in your area, or organize one yourself if there’s not one near you. It just takes a circle with a fifteen-mile (24 kilometer) diameter and some initiative any time between December 15 and January 5 inclusive. Try it.

Happy Thanksgiving!

By

Thursday, November 24th, 2011

They’re back! Well, maybe not the same individuals. Turkeys only live in the wild for three or four years. And the last time we had turkeys on our deck scarfing birdseed out of my feeders was five or six years ago.

That last time was in the spring when a small flock showed up every morning and hung around for a week or so. They caused quite a stir in the neighborhood before wandering down the river to a yard where the owner put out large bowls of dog kibble for them to feast on every day.

Then a neighbor called animal services because she was afraid that her dog would get maimed by the turkeys as it challenged them for the dog food. As we all know, there are wild turkeys, and there are real TURKEYS.

Those wild turkeys were quickly rounded up and, I hope, set free in a forest somewhere outside the city.

My yard is no forest but it’s a pretty attractive place for wild turkeys. In addition to the birdseed, there are plenty of acorns, some berry bushes, slugs and grubs in the garden, probably an amphibian or two – regular staples in a turkey’s diet.

In the sunlight, turkeys are quite spectacular looking. The subspecies found here is the Eastern variety (Meleagris gallopavo silvestris). Granted their heads look like they got too close to a power mower that shaved all the feathers off and left them with a blue, purple and red scar. But their feathers have an iridescent quality on a warm brown background. And the tips of their tail-feathers are yellow-bronze in color with a band of purple-black just before the ends. I can see why some First Nation peoples used them in their ceremonial headdresses.

Our Canadian Thanksgiving was over a month ago; so I don’t think the turkeys took refuge in my yard to escape the holiday-meal hunters. I hope they stick around. It’s amusing to see them stretch for their breakfast every morning.

No collection of purchased objects, no matter how expensive or exquisite, can match the pleasure of finding a wild animal unexpectedly appearing in your life.

Bumble Bees

American Bumble Bee

As I was sweeping my back patio this week, I found a dead and desiccated bumblebee. Since I’m no entomologist, I have no idea whether it was male or female. I hope it was a male.

Unlike honey bees – which hive together in large numbers over the winter, bumble bees rely solely on their queen bees for the propagation of their colonies. The workers and drones all die off each fall. The queen bee spends the winter alone in the ground or in some other warm place.

When I first came to Manitoba, I was delighted to find bumble bees here because I thought the winters might be too cold for their survival. But they are hardy critters; they live as far north as the Arctic Circle. They’re found on Ellesmere Island, in fact, less than 500 miles from the North Pole. They’re especially familiar on the prairies and mountain meadows.

Like most other kids, I loved finding bumble bees when I was a kid. Back in the days when yellow and black were the colors of warning signs rather than florescent lime green, bumble bees seemed to be equipped with their own furry warning coats.

With their deep, rumbling buzz, their chubby bodies, and seemingly undersized wings, they were not only noticeable, they were the easiest flying insects to catch. I regret to admit that many a bee died in a Mason jar with a nail-punctured lid while in my youthful custody.

Nowadays, they too are in serious decline. A University of Illinois researcher, Sydney Cameron, did a study of eight of the fifty species of US bumblebees a couple of years ago. Four of the eight are in serious decline. A 96% decline.

Kids and I aren’t the only ones who’ll miss them. Since they pollinate tomatoes, cranberries, blueberries, raspberries, strawberries, and apples, we all should take heed of their possible demise.

Crows

By

Friday, October 21st, 2011

At first I thought they were mobbing a Great Horned Owl. Or maybe a rare migrant owl that made the mistake of settling down for the day in their favorite roosting spot. Crows can raise an almighty racket when there’s an owl around.

I knew right where they were – two and a half blocks away in a park where they often congregated for the night, but noisy enough to be audible even at that distance. So I went back inside to retrieve my binoculars to search for whatever was getting their dander up.

As I walked to the park, I couldn’t see how many were flying in from other directions. But wave after wave of crows approached from the south. They just kept coming and coming — in flocks of between 20 and 60 birds. Eventually the crows I counted totaled between 500 and 600.

As there was already a fierce clamor in the park when I started counting, the number was clearly more substantial — and positively Hitchcockian in its scariness. Upwards of a thousand, I’d guess-timate.

And not an owl to be found. The crows were simply cawing to each other, excited probably at the prospect of another collective migration to the south.
The next night the very same thing happened. Just before dusk with the sky still blue and the aspen leaves a bright yellow, they once again came from all over to gather and amass, gather and amass.

And then, overnight, they were gone.

I’d never before seen a massing quite like it. Certainly not in my neighborhood. What an immense, noisy bunch!

If a flock of them is called “a murder of crows”, this was “a genocide” of them!

Tiger Salamander

By

Thursday, October 13th, 2011

Manitoba’s weather can change dramatically in a matter of hours. Thursday it was clear, sunny and hot. Record-breakingly hot. 31.1 degrees Celsius (about 88 degrees Fahrenheit) – the hottest October day ever. On Saturday we were walking the dikes of Whitewater Lake in mitts, toques, and winter jackets, wondering where the sun and warmth had gone.

We’d car-pooled there to check on the migrating waterfowl, and we were all nervous the change in the weather would chase them all away. But the place was still teeming with ducks, geese, shorebirds, and even egrets.

The change in the weather did catch one thing by surprise, however. We found a Tiger Salamander (Abystoma tigrinum) laying on a path, evidently waiting for the return of the sun. It was very lethargic and cold to the touch.

Tiger Salamanders are usually pretty secretive. This one had probably emerged from its burrow during the warm night in search of its usual diet of insects and worms and got caught off-guard when the cold front moved in.

Although Tiger Salamanders can have brilliant yellow splotches or stripes on a dark brown, black or green base (like a tiger), this was uniformly dark greenish-brown and had almost no markings at all. It was curled up in a ball, its chunky body, ten-inch length, and thick tail entirely disguised. Half our group passed by it unnoticed, thinking it was black bear scat.

At Whitewater Lake Tiger Salamanders are at the northern edge of their Manitoba range. It’s amazing that these amphibians can survive here. The lake in some drought years can shrink to almost nothing, and waterfowl can die of botulism during those years. Somehow the hardy Tiger Salamanders can adapt pretty well to dry conditions.

Adapting to a dramatic change in the Manitoba weather is an entirely different proposition.

Woolly Bears

By

Thursday, October 6th, 2011

A clear, blue sky. The landscape softened by leaves and grasses turning from green to yellow and brown. The pleasant rustle of downed leaves underfoot. A perfect day to head to Oak Hammock Marsh.

At this time of year The Marsh proves why it’s an IBA (Important Bird Area). Hundreds of shore birds, thousands of ducks, and tens of thousands of geese stop here in migration every day.

As I walked a path to get the sun behind me, I almost stepped on a Woolly Bear (Pyrrharctic Isabella). It caused an intense flashback.

Thirty years ago I strapped my two young daughters into their car seats and took them to The Marsh to show them the wonders of a Manitoba waterfowl migration.

The sky then was dark with geese, and their plaintive honking could be heard almost a kilometer away. I instructed my girls on the differences between the varieties of ducks and geese. I pointed out how geese wiffle down onto the water. I showed them the dabbling ducks and the diving grebes, and I asked them to count the seconds the grebes were underwater. The girls couldn’t have been less interested.

What fascinated them were the Woolly Bears. While I was gazing up, the girls were staring down at the little black and copper caterpillars (also known elsewhere as Woolly Worms, Fuzzy Bears, and Hedgehog Caterpillars).

I didn’t know much about caterpillars then, but I decided to make it a teaching moment anyways – even though what I told them was dead wrong.

The Woolly Bears, I said, were larvae that would turn into wondrous butterflies in the spring. In fact, they become orangey-yellow Tiger Moths. And I indicated that you could tell from their colors whether the winter would be warm or cold; the blacker they are, the longer and colder the winter will be. In fact, the coloration of the 13 segments of the Woolly Bears is the result of their age and feeding habits.

For the rest of our time there I looked at birds, and my daughters searched for more caterpillars.

I didn’t realize ‘til we got home that they were not just searching, they were collecting. They were hoping to hide the Woolly Bears so that in spring their bedrooms would be full of “flutterflies”.

Their seatbelts had actually mashed most of the larvae (at least a dozen each) in their jacket pockets. Icky, greenish goo stained, those jackets.

We only saved a few, putting them outside in the grass and hoping their natural cryoprotectant (anti-freeze) would help them survive ‘til spring.

By Spring my daughters had forgotten their precious Woolly Bears.

Hawk vs. Flicker

By

Wednesday, September 28th, 2011

Birds

It took me far too long to finish rebuilding my deck. But it was unexpectedly warm and sunny on Sunday. So, I lollygagged while replacing the joists and the floorboards. It was too nice to work hard.

In the middle of the afternoon a couple of flickers looped into my backyard and began searching for ants and grubs. They provided a pleasant distraction. Until….

In a flash an immature Cooper’s Hawk swooped in and struck one of them. It tore the poor bird apart in short order, scattering feathers in a small circle and feasting on its flesh. I didn’t intrude (it would have been too late anyways), content to watch what Tennyson called “Nature, red in tooth and claw” – or in this case “red in beak and talon.”

Flickers are easy targets. They’re big and colorful, they’re rather slow, and they sit out in the middle of open fields as if they have a big target on their backs. I’ve seen the remnants of quite a few of them over the years in a nearby park, where they’ve nested virtually side by side with Cooper’s Hawks. Symbiosis in action.

Flickers are such easy prey that juvenile Sharp-shinned Hawks will practice taking them down even though the flickers are too big to catch and eat. The sharpies will just dive bomb them, spook them a bit, and probably fly off chuckling to themselves.

It got me thinking about bird migration. I’ve heard that Northern Saw-whet Owls will move along with the Hermit Thrushes as they migrate south, following the food. I wonder if Coops follow flickers. I hope not.

Even though I can see over a hundred flickers a day at this time of year, it seems that these are one of the species that aren’t as plentiful as they once were. And Cooper’s Hawks are more abundant. I don’t like those odds.
