September is the peak of autumn bird migration, and billions of birds are winging their way south in dramatic pulses. A new study published in the journal Science reports that scientists can now reliably predict these waves of bird migration up to seven days in advance. The study details the underlying methods that power migration forecasts, which can be used as a bird conservation tool.

In this study, the researchers quantified 23 years of spring bird migration across the United States using 143 weather radars, highly sensitive sensors that scientists can use to monitor bird movements. They filtered out precipitation and trained a machine learning model to associate atmospheric conditions with levels of bird migration countrywide. Eighty percent of variation in bird migration intensity was explained by the model. To view a radar loop depicting bird migration during spring 2018, click here. » Continue Reading.

I usually hear the kingfisher before I see it. If I’m reading by the lake, its harsh, rattling call gets my attention. I look up to see the flashy blue-and-white bird fly to a new perch or hover over the water scanning for small fish and crayfish. If I’m kayaking, I try to follow it along the shore as it moves from one overhanging limb to another. This lasts for about two moves: they are easily disturbed and are fast fliers.

Stalking the bird recently, I began to wonder about its nest. As common as belted kingfishers are, I didn’t know anything about their domestic arrangements. As it turns out, my kingfishers likely consider this lake better for noshing than nesting. The lake’s rock-bound shore lacks the type of steep earthen bank the birds need to dig a burrow. Kingfishers are among the few birds in North America that nest in cavities they excavate themselves. » Continue Reading.

One afternoon in early June, a small brown bird swooped down in front of our kitchen window. I wondered where it had swooped from when, a minute later, I saw it fly back up, with a sliver of straw in its beak. I went out the back door, onto the deck, in time to see the bird exiting the shower vent on the gable end of the house. It was a house wren, and it was building a nest in my house.

Tip to tail, house wrens, Troglodytes aedon, are generally about 5 inches long and weigh about .4 oz. – half the length of the average robin and far lighter. They have brown feathers, longish beaks, and tails that are often tipped upwards. These tiny birds have one of the most expansive breeding ranges of any songbird, stretching from southern areas of Canada, to the far southern reaches of South America. In between they are found across the entire continental United States, the West Indies, Mexico, and Central America. » Continue Reading.

Years ago, friends and I spotted a group of huge nests high in the trees along the edge of a large pond: a great blue heron rookery. From across the water (a respectful distance to avoid disturbing the birds), we observed the goings-on through our binoculars. Adult herons flew in and out of the colony, their long necks and heads folded back onto their shoulders in an S-shape, wings beating slowly, long legs trailing behind.

As a parent approached its nest, the young stood up eagerly, jostling each other and clamoring for food. Alighting on the stick platform, the adult quickly inserted its long beak into each nestling’s throat, and with a pumping motion, regurgitated a nutritious soup, which likely included fish, crayfish, or frogs. » Continue Reading.

New York State Department of Environmental Conservation (DEC) has announced the launch of two birding challenges for 2018 through the State’s I BIRD NY program. I BIRD NY was launched in 2017.

New York habitats support more than 450 different bird species. There are also 59 Bird Conservation Areas across the state. » Continue Reading.

It is traditional backwoods wisdom to avoid getting between a mother and her babies, and while this advice usually pertains to the black bear, it could also apply to several other forms of wildlife that reside in the Adirondacks.

In late spring many infants are emerging from the safety of their den or nest and most mothers try to provide some form of protection from potential danger to their babies. Perhaps the most remarkable display of parental courage for a creature of its size is seen in the hen ruffed grouse. This bird will aggressively confront and challenge any human that happens to come too close to its recently hatched chicks. » Continue Reading.

Somewhere I read that up here in the Adirondacks you should not feed the birds after March 31st. I forget the exact logic. The article provided one of those explanations that, you know, sounded quasi-plausible, but might have just been something that a guy would tell his wife so he wouldn’t have to go out into the yard and top off the feeder for the 7,000th time this year.

I think it had to do with birds needing to fend for themselves, and several other sundry character issues that I hadn’t thought of as applying to wildlife. I sort of understand, though. It’s like all our kids thinking that food comes from a supermarket instead of a farm. Maybe bird-parents sit around Starbucks saying, “Fledglings today, do you believe it? They think everything comes from a feeder. They don’t realize all the work it takes to peck it out of a seedhead.” » Continue Reading.
