Throwback Thursday by Jungle Pete: Buffet Mixer

There are a variety of benefits to doing things in groups. Consider the last cookout you attended. Someone else bought the food. Someone else cooked and cleaned up. There was less risk of being eaten by a predator. Communal roosting makes sense too. Eating and roosting together makes sense for Great Egrets, Snowy Egrets and White Ibis.

More ears and eyes means predators are at a disadvantage during a sneak attack. While roosting, huddling can conserve warmth for those with the best spots in the roost. The downside is when you head out for breakfast in the morning everyone follows. The older and experienced birds tolerate social parasitism in exchange for safety in numbers. There is a pecking order and bigger birds can dominate others in the flock.

Finding food is also easier with many eyes looking. Once located, the buffet commences. Here a flock of Great White Egrets, Snowy Egrets and a few White Ibis have found a high concentration of fish and frog eggs to feast on.

Around the outskirts of the buffet are Little Blue Herons who are exhibiting commensalism. As the Egrets and Ibis stir things up, the Little Blue Herons feed on what the rest of the birds are not interested in. Essentially commensalism is when one species feeds among others and benefits without harming or benefiting the main species. In this case the Little Blue Heron is the guy that came to the party with the friend you invited. Little Blues are twice as successful when feeding commensally as opposed to individually.

May marked the end of the dry season in Florida which generally runs from December through May 15th. As the wetlands begin to fill with water and prey species re-colonize the marshes and swamps, many of the wading birds will rely less on communal feeding and venture out to forage solo. After a long day of hunting, it’s back to the communal roost for an evening of preening and sleep. Party on.

Peregrinations by Gene Walz

We’ve had a drearily long winter in Manitoba. Six months of freezing temperatures. Even for wintry Winnipeg this is L-O-N-G. It’s May, and big piles of snow still lurk in some shady places. AAARRGH!

The cold and the long-lasting ice and snow (not just in our province but in the Dakotas south of us) have delayed bird migration here. Everything is at least two weeks behind schedule.

Disruptions from routines, even the tardy arrival of spring, can have some very beneficial effects.

Until this year we never suspected that more than a handful of Peregrine Falcons migrated through Manitoba. Then, on April 25, 22 peregrines passed the raptor migration watch at Windy Gates, Manitoba on the North Dakota border. The next day, an astonishing 46 peregrines were recorded. Wow!

Less than 50 years ago, there was only one peregrine sighted in all of Canada east of the Rocky Mountains. Now we have scores zooming through Manitoba in a matter of weeks!

Because we so often hear of declining bird populations, these numbers are both amazing and heartening.

A peregrine recovery program started here in the late 1980s. Since then up to four pairs of these gorgeous raptors have nested in two southern cities in Manitoba every year. With cliff sides and now tall buildings as their favorite nest-sites, few of us thought much about the possibility that other peregrines could be passing through.

Thanks to hawk-watches and the internet, we now realize that the Pembina Valley is a major flight path. Peregrines that breed in Nunavut and Nunavik in the territories north of Manitoba commonly fly through here on their way north to arctic-nesting sites at Rankin Inlet (on Hudson Bay), Igloolik (on the Melville Peninsular), Steensby Inlet (on Baffin Island) and elsewhere.

Peregrines are nesting north of the Arctic Circle in places with few cliffs and fewer skyscrapers. Who knew?!

Photo Essay: Brown Pelicans by Charlie Rattigan

Boca Grande, Florida Gasparilla Island  (26.738520 , -82.264413)

Just after sunrise on April 10, 2013 nearly 100 Brown Pelicans, Laughing Gulls, and Common Terns began a feeding frenzy several meters off shore from the Gulf beach just south of Gasparilla Island State Park.  Of the many pelicans feeding, it was not unusual to see as many as five or six birds rise up and dive in quick succession.  The activity lasted well over an hour and was repeated the next day.  The weather was bright and sunny and the wind out of the east and calm.  It was only these mornings that I saw this behavior and suspect that when the wind shifted to a southwesterly direction the fish moved way from the shore.

Today birders and naturalists around the world are celebrating the 228th (this year) birthday of John James Audubon, the French-American naturalist and artist.

An iconic figure in ornithology, Audubon revolutionized the practice of field identification, created fantastical yet realistic works of art, and worked hard to follow his passion of illustrating birds. Indeed, his name is emblazoned across the top of this page – now the figurehead of an organization synonymous with birds and conservation.

Here are some brief – and perhaps less-known – facts about Audubon:
1. Audubon was born in Haiti, raised in France, and moved to Pennsylvania at age 18 to avoid conscription to Napolean’s army.
2. After moving from southeastern Pennsylvania to Kentucky (with his wife Lucy), Audubon was briefly thrown in jail due to bankruptcy from a failed business venture.
3. Besides the familiar collection of his paintings, Birds of North America, Audubon released Ornithological Biographies (life histories of various bird species) and Viviparous Quadrupeds of North America (a compilation of illustrations and text, started by Audubon and completed by his sons after his death).

His paintings, though, are what define him for modern birders. The birds’ unique poses – that attempted to bring some life and nobility to the dead specimens he often used as guides – invoke the extraordinary from the common.

It is interesting to reflect back on the days before high-quality optics were widely available for the study of birds. It was acceptable- actually the norm back then- to go out and “collect” specimens, a euphemism for killing birds to study. Studying these lifeless forms formed the basis for his artwork, and it is actually quite amazing that he was able to incorporate such life and action into his paintings. I can only imagine what his artwork would have looked like if he had been able study live birds in equal detail. Would his paintings have become as iconic?

So let’s celebrate the artist, his legacy, and the organization that bears his name. Happy 228th birthday to John James Audubon!

Great Blue Herons are Back in Manitoba

Great Blue Herons are Back in Manitoba by Gene Walz

Those birds brave or foolish enough to return to Manitoba this week shine in the sky as if they are lit from within. And lit with a 500 watt bulb.

The snow has not melted here yet. Still a 2-foot mattress of white in many places. The sun reflecting off the snow turns raptors and geese into shining bird-ghosts, their white undersides brighter than bright.

Even birds that don’t have white undersides look white. A Great Blue Heron flew over me, and it shone so brightly that for a second I thought it might be a white morph (Great White Heron) or an intermediate (Wurdeman’s). A closer look revealed its silvery blue feathers shining like a brand new quarter.

Great Blue Herons look so relaxed, so laid-back when they fly. The wings beat slowly and steadily. The long neck coils back on itself in a kind of lazy slouch. Not determinedly stretched out straight in front like cranes or geese.

I have no idea how this intrepid heron is going to find food. The rivers are still frozen two feet thick. (Ice-out usually occurs on April 1.) Marshes and streams  may not thaw for a month. It’ll be a while before the fish and frogs and slugs and bugs that suit a heron’s palate will make an appearance.

Once the ice melts and the heron’s food supply make an appearance, this bird stalks its prey with the proverbial patience of Job. It stiffens into a feathered statue, its bill and long neck poised like a javelin. Then it springs!

But that’s for later. If a heron were to try that now, it would shatter its bill into splinters and end up with a very sore neck. I hope it’s got a good reserve of fat from its warmer wintering ground. It’s still winter up here.

Throw Back Thursday: Variations in Rough-legged Hawks

Rough-legged Hawk

Rough-legged Hawk by Lisa Densmore

Location: Lima, Montana

If you’re wondering where Lima (pronounced LI-ma, like the bean), Montana is, you are not geographically challenged. With due respect to the residents of this small ranching community in the southwestern part of the Treasure State, the only reason Lima entered my life was because we passed through it on the way home after a weekend in Idaho. I’m not apt to forget it. It took a long time to travel through Lima, not due to traffic – we might have seen two cars in two hours on the open road on which we traveled – but because we saw so many Rough-legged Hawks (Buteo lagopus).

Rough-legged Hawk

Rough-legged Hawk by Lisa Densmore

They perched everywhere, on the irrigation pipes, on the tops of electrical poles, on fence posts… In this hawk-rich environment, I gained a new appreciation for this rodent-eating raptor, which is on the large side for a buteos, averaging 19 to 24 inches tall. With so many of the species in one place, I realized how much variation there could be from one to another. The typical Rough-legged Hawk has a dark belly, though it may be blotchy. A black patch normally shades the carpal joint where the wing bends, but not always or it might be very small. The wings have lots of white on the underside, and its white tail has a black band near its end, but the black morph has a mostly dark tail. ID-ing a Rough-legged Hawk can be challenging if you don’t already know the bird. It’s more diverse than Grand Central Station during rush hour. Fortunately, it lives in a less populated environment than mid-town Manhattan, making it easy to spot.

I enjoyed seeing its color variations. The phenomenon is not unique to Rough-legged Hawks. While each avian on my Audubon Birds app has a common look, variations occur. Have you seen birds-of-a-color that really are not?

The Birds of Hawaii

The Birds of Hawaii by Gene Walz

Hawaii is not the place to go if you’re intent on adding to your Life-Bird list. There just aren’t that many unique native birds left on the islands.

Since “civilization” reached Hawaii about 200 years ago, over 30 native bird species have gone extinct.  Recent evidence seems to suggest that more species were killed off by the original islanders; bird plumage played a huge role in their costumes and decoration.

When I was in Maui in January, I did see about three dozen species of birds. But most of them I could have or had seen elsewhere. Cardinals, skylarks, mannikins, white-eyes, the usual Euro-trash, some common shorebirds and waterbirds from the Americas, and others.

There was even a colony of Peach-faced Lovebirds thriving in south Kihei – so new that they aren’t yet in the bird guides for the island.

I take delight in finding and identifying all kinds of birds. But it’s actually disheartening to see non-tropical birds on tropical islands. Especially if they are contributing to the demise of the native birds, the endemics.

One of the last places to see Maui endemics is in Hosmer’s Grove, a canyon near the top of the extinct volcano Haleakala on the east side of the island.

I went there twice and managed to get long, satisfying views of the Apapane, Amakihi, Alauahio, I’iwi — all bright, active, wonderful bird finds. But I missed the Maui Parrotbill and Crested Honeycreeper, two high-priority target-birds that are rapidly disappearing on the island. A huge disappointment.

Nearby I found several NeNe (Hawaiian Goose), and in the shallows at Kealia Ponds I easily spotted Hawaiian Coots, Hawaiian Ducks, and many Hawaiian Stilts.

I went to Maui for the whale-watching, the seafood and fresh fruit, the beaches, and the warmth. It would have been great had I been able to tick all the bird species I targeted. I guess I’ll have to go back. Damn!

Reenergizing the Red-tailed Hawk

Reenergizing the Red-tailed Hawk by Josh Haas

I’m betting the last time you saw a Red-tailed Hawk, you didn’t give the bird a second look. When birding and creating lists for the day, there are species that tend to get boring. As one of the most prevalent hawks in North America, the Red-tailed Hawk fits this category for many birders. But I’ve found the bird is worth a closer look.

Red-tailed Hawk

This raptor is a dynamic hunter that tends to go after small mammals, amphibians, reptiles and more. It’s opportunistic nature is one reason the bird is so pervasive and, hence, boring to birders. One type of prey missing from the list is small perching birds. And while it’s true they’re not necessarily built for hunting this type of prey, once while hawk watching at the Whitefish Point Bird Observatory I saw an individual display the power and versatility needed for the task. Flying at tree-top level with a strong steady wing-flap, the bird suddenly fanned its tail in such a way so as to flip sideways and nab an unsuspecting Northern Flicker off a dead tree. My binoculars came down, a smile came over my face, and for me the Red-tailed Hawk became a little more exciting. More recently, during a Detroit River Hawkwatch count, I saw a beautiful Northern Harrier circling above the count site when a Red-tailed Hawk unexpectedly stooped into view in pursuit of the Harrier. Enthusiasm soared among the onlookers as the Red-tailed Hawk continued after the Harrier. The aerial battle demonstrated to all who had seen it that this large-bodied Buteo could not only keep up with other agile raptors but maneuver like a Merlin as it dipped and raced around the skies. Yet another experience where for me, the Red-tailed Hawk became a little more exciting.

These are just two quick examples of how the Red-tailed Hawk is more than a modest soaring bird living around our highway systems. The large hawk is nothing short of amazing. With its large powerful feet, snappy wing flap, and keen hunting techniques, this adaptable bird can adjust easily to many habitats and situations. My hope is the next time you find yourself viewing a Red-tailed Hawk through your binocs, you’ll linger a bit longer. It might just do something for which the bird becomes a little more exciting.

Getting Ready for Spring: Horned Larks

Getting Ready for Spring: Horned Larks by Gene Walz

A winter tradition here in Manitoba that I missed this year usually involves jumping in the car on a clear, snow-free day in early February (on or near an accompanying friend’s birthday) and heading out to find Horned Larks. I spent this winter in a warmer, mostly snow-free zone. So the larks weren’t the first returning birds of the year for me. Bald Eagles beat them.

I’ve never considered Horned Larks the true harbingers of spring. They don’t qualify because every year I hear reports of Horned Larks that over-winter here. And the migrating larks usually come back to Manitoba far ahead of the official arrival of spring on March 21, and well before the snow melts (the actual arrival of spring sometime in April). But I like to celebrate their hardy appearance.

Any bird that sticks around from November to March or comes back here in the dead of winter has got to be special, deserves a salute, a toot of the horn, especially a bird so delicate.

Twenty-one subspecies of the Horned Lark can be found in North America (another 19 around the world). Subspecies associated with Manitoba, the Canadian Prairies, and the Great Plains include Eremophila.aalpestris enthymia, E.a. leucolaema, and E.a. praticola.

Dusty brownish-grey above and white below, they are best distinguished by the black, yellow and white markings on their heads and necks (black “horns” aren’t often visible) and their white outer tail-feathers.

They prefer open areas with short, sparse vegetation — croplands, fencerows, road rights-of-way, pastures, and recently cut hayfields. The gravel mile-roads in farm country southwest of Winnipeg are the best place to find them.  They flit along the road edges, folding their wings after each beat and never flying very high or far from the car.

Because they are grassland birds, their numbers are diminishing. I’d hate to see them disappear completely. They cheer me up considerably in February when I usually need it most.

Throwback Thursday: Winter Sparrows

Throwback Thursday: Winter Sparrows by Drew Weber Originally Posted 2/16/12

As I related in my last post on ducks, the winter months can appear to be a slow period for birding. However, in addition to ducks, there is another group of birds that is more diverse and easy to observe in the winter compared to the summer: the sparrows.

Sparrows have always had the bad rap of looking the same and being difficult to identify. They are often lumped into a group of birds called the “lbj’s” or “little brown jobbies”: birds that all look the same and aren’t worth the time it takes to identify them. To these folks I say: nonsense! With some patience, sparrow identification is pretty straightforward with most species having obvious features that can be used for identification.

Song Sparrow

Across much of North America, the Song Sparrow is the default sparrow. It is worth the time to really get to know the field marks of Song Sparrows. It has smudgy red-brown streaks on its chest and a spot in the center of its chest.

White-throated Sparrow birds

During the winter months, one of the most common sparrows is the White-throated Sparrow. Aptly named, the White-throated Sparrow has a bright white patch on its throat, as well as white stripes on its head that turn bright yellow near the beak. These are one of the most common feeder birds in many areas, especially when snow has covered up their more natural food sources.

White-crowned Sparrow

A close relative, the White-crowned Sparrow, has bold black and white barring on its head. White-crowned Sparrows are less common at feeders, often tending to hang around overgrown hedgerows along fields. Depending on the habitat around your yard, you may be lucky enough to host these large sparrows.

Dark-eyed Junco

Another easy to identify winter sparrow is the boldly patterned Dark-eyed Junco. Dark above and white below, the little twittering noises of these birds as they scavenge for seeds under my feeder always makes me happy. Juncos vary widely in their plumage across their range and it can be fun to scan through the flocks, looking for a ‘pink-sided’ junco.

American Tree Sparrow

The most northern of the winter sparrows is the American Tree Sparrow. With its red cap, it is superficially similar to the Chipping Sparrow, a summertime resident. However, the bi-colored bill and spot on the breast separate it from Chipping Sparrow.

These are the most common sparrows you will encounter during the winter in the northeast. Most of them have pretty distinctive features, so the next time you see a sparrow hopping under the feeder or in the shrubs, take the time to identify it and add it to the list of birds that you can quickly recognize.
