Woodcock are being seen and heard at dusk, phoebes are showing up slowly but steadily, mixed flocks of blackbirds are headed north, and the weather is sunny and warm one day and freezing and wet the next. It must be March in New England.

As we get ready for migration to pick up steam, here’s what readers have been reporting over the last few weeks. Bill from Keene wrote to say he’s hearing spring songs from the woods, which is always a good sign and pleasing chorus. Spring peepers, wood frogs and some birds are starting to call. I’ve heard cardinals almost daily now, which is a most welcomed, cheerful song.

Jeannie from Marlow wrote to say she has had upwards of four red-breasted nuthatches visiting her feeders at once. I thought my two-at-a-time visits were good. Jeannie also sent along a terrific photo of a barred owl having its feathers blown around by a strong wind. The photo may be found at www.birdsofnewengland.com under the “Reader Submitted Photos” category.

Jane from Marlborough wrote, questioning whether a small bird of prey she saw take a chickadee could be a merlin. Merlins are small falcons that breed mostly north of New Hampshire, but some do breed in the state and many pass through during fall and spring migrations. So it is very possible that her bird in question was a merlin.

Here’s what the N.H. Fish and Game website says about the merlin’s range: “Expanding range southward in NH. Currently breeds in the north and at scattered locations in central and western parts of the state. Occurs statewide during migration which peaks during September and early October; occasionally winters along the seacoast or in southern suburban areas.”

Thanks to the Keene Lions Club for having me as a guest speaker via Zoom last week at its meeting. I enjoyed meeting everyone virtually and appreciated the many thoughtful questions at the end. A question was posed that I didn’t have the answer for at the moment. I had referenced early in the presentation the 2019 study that shows there has been a decline of 2.9 billion birds in the U.S. and Canada over the last 50 years. The question came up as to what percentage that number represented. I thought it was a great question as numbers are sometimes presented to show a point, but proper context is missing.

I looked back at the study and found out that the 2.9 billion missing birds represent a 28 percent decline — roughly down from 10 billion adult breeding birds to 7 billion. That is a substantial number no matter how you look at it, but when you consider birds of certain habitats have declined by more than 50, the number becomes even more stark. Grassland birds, for instance, have declined by 53 percent since 1970, according to the study. That is fewer than half of the meadowlarks, bobolinks and more of our favorite grassland birds remaining.

On the bright side, which I was reminded of when I looked back on the study, numbers of waterfowl, raptors and woodpeckers have increased in the last 50 years.

The study, by the way, is entitled “Decline of the North American avifauna” and was conducted by researchers from several organizations such as Cornell Lab of Ornithology, American Bird Conservancy and National Audubon Society.

I hope everyone is ready for spring migration. Be sure to let me know what you’re seeing.
