The latest on the birds

Fall means migration in the bird world and we are in the thick of it!

While we sleep thousands and thousands of small migratory birds are winging their way south over cities, villages, farmlands, and forests. Some are making incredible flights thousands of miles in length.

One bird, the Bobolink,  that was nesting in hay fields around the Adirondacks this summer, has gathered into flocks and are now flying to the very southern reaches of South America. As we proceed into autumn and winter, our South American neighbors are feeling the tantalizingly warm beginnings of spring. As a result the Bobolinks will spend their summer (our winter) in Argentina eating rice!

Hawks, eagles, and falcons, also called raptors, are all on the move south these days. Many birders in our area will be heading over to the Lake Champlain Valley to watch the migration of thousands of Broad-winged hawks as they form roiling “kettles” of circling birds that are riding warm air thermals rising off the Valley floor and gently moving the birds south. Some Broad-winged hawks have the very sweet winter destination of Costa Rica.

Warblers and vireos are also commonly found these days grouping up into feeding flocks that filter through our Adirondack woodlands in search of late caterpillars, moths, and spiders. I find it amazing that these tiny birds are migrating hundreds of miles each night while we slumber.  Read more here.

Before long the autumnal blue skies will be filled with south-bound Snow Geese and Canada Geese. Filling our ears with that homecoming-sound, the geese passing overhead aren’t going too far for winter. They’ll end up in the Chesapeake and Delaware Bays.

But the big news in the birding world was just released today in the form of a long-awaited email. It’s the traditional analysis of Canada’s cone crop review.

The what!?

Each autumn, a Mr Ron Pittaway of the Ontario Field Ornithologists, gathers information from many birders around Canada and northeastern US about how the current pine, spruce, and other cone-bearing trees are doing this year. Are they producing lots of cones for the winter finches, waxwings, and other seed-eating birds?

2009 was not a very good year for winter-visiting finches here in the Adirondacks. So what does Mr. Pittaway have to say about this year? Read here!

Cutting to the chase, it looks like a couple winter finches might filter down our way from Canada. Possible visitors of Pine Siskin, Common Redpoll and Purple Finch might grace our seed-filled winter feeders. But if you enjoy skiing or snowshoeing, then it’s worth a perambulation through your nearest woodlands this winter to check out the avian visitors.

Background noise

Now is a wonderful time to be listening to that late summer background “noise” that we all hear but never pay much attention to. I’m referring to the myriad of insect sounds that can be heard on these hot and humid days.

Take some time out of your busy day and give a listen to the field crickets, ground crickets, and tree crickets in your yards, and neighborhood. Here’s a great site to help you learn these insect sounds and also learn a bit about their ecology and life history. Click on “Online Guide” for details. It’s worth looking over just for the great common names they’ve been given!

I have fall field crickets, and a species(still trying to figure out which one) of tree cricket calling in my yard and nearby woods. If I listen carefully I can hear the “typical call” of the fall field crickets with their constant “chirps”. But overlaying all the other calls is the very high-pitched whine of a species(?) of tree cricket.

Who knows, maybe some day I’ll hear a sword-bearing conehead!
