For the Birds: Breaking down hawkwatch season

The fall hawkwatching season is winding down. Raptor sightings at the various dedicated locations are slowing down, with only a handful of birds counted each day as November progresses.

It’s a good time, therefore, to check in to see how the various hawkwatching sites fared this year. New England has several popular sites, but Pack Monadnock at Miller State Park in Peterborough is New Hampshire’s most active and popular site. The hawk count is a project of the Harris Center for Conservation Education in Hancock.

As of November 11, and according to hawkcount.org, overall numbers look good in 2025 at Pack Monadnock and outpace the number of hawks counted in 2024. It may be noted, however, that 2025 numbers are below the several years prior to 2024. With the official count season ending there on November 20, Pack Monadnock will end up with about 8,500 hawks counted for the fall.

The term hawk is used somewhat loosely here as the count includes hawks, eagles, ospreys, vultures and falcons. The hawks are counted by experts and volunteers who sit at the peak of Pack Monadnock and watch the birds soar in from the north. I’ve been to several hawkwatch sites and am always amazed at the skills of the official counters. They see and identify most of the birds long before the bird is even in view of most other people. 

Before reading on, can you guess what hawks are counted the most? Hint: One bird stands head and shoulders above the rest in terms of sheer numbers. Another hint: It’s not the red-tailed hawk, which I assume would be many people’s first guess. 

That bird is the broad-winged hawk. Of the roughly 8,500 birds counted at Pack Monadnock this fall, nearly 6,000 (5,821 to be precise) were broad-winged hawks. A distant second is the sharp-shinned hawk with 1,133. 

Simple math (even though I used a calculator) shows that broad-winged and sharp-shinned hawks account for more than 80 percent of the total birds counted. The number drops sharply again for the third-most-counted “hawk,” the turkey vulture, with 222 individuals counted. 

For all you stat geeks out there (like me), the next birds in line are American kestrel (196), Cooper’s hawk (190), osprey (167), bald eagle (159), red-tailed hawk (154) and northern harrier (121). Remember, these are not final numbers, but they will be pretty close.

Although “only” five golden eagles were counted, I’m sure each one elicited some oohs and aahs from the crowd. 

According to hawkcount.org, a page that aggregates hawkwatch sites across the country, a few New Hampshire schools performed mini-hawkwatches this September. Concord School District did a week-long program and counted, you guessed it, mostly broad-winged hawks. Turkey vultures were also counted in fairly high numbers.

Interlakes Elementary School in Meredith did a two-day count and found an impressive 1,350 broad-winged hawks, including 1,257 in a single day. Sharp-shinned hawks and turkey vultures were the next highest counts. 

The aptly named Hawk Mountain Sanctuary in Kempton, Pennsylvania, is perhaps the most well-known hawkwatch site in the East. Similar to Pack Monadnock, broad-winged hawks were the most numerous, accounting for 9,015 of the 13,436 overall birds counted. Sharp-shinned hawks were next with 1,530. 

If you missed this year’s hawk counts, mark your calendars for next year. You don’t want to miss mid-September, which is when the number of broad-winged hawks peaks. More than 3,000 broad-wingeds were counted on September 14 at Pack Monadnock. The conditions must have been right just on that day. October is a good month to see a variety of species, while things start to slow down by November.

The end of hawkwatching season means that winter is right around the corner. Winter may bring out a bah humbug from many, but it is also a great time for birdwatching, just in a different way.

For the Birds: Fall migration under way

It seems like just yesterday we were welcoming back the warblers and other songbirds during spring migration and here we are at fall migration already.

Many of the birds we saw in the spring heading north will look the same on their southward journey. Many others, however, will look different. 

Some, like male scarlet tanagers, will bear little resemblance to what they looked like in the spring. When we saw them in May and June, they were the most brightly colored birds in the woods. A sighting always yielded a gasp of excitement as we wondered how a bird in New England could be so brilliant. After the breeding season, however, they molted and are now dull yellow with less shiny black wings. They are still awesome-looking birds but not the striking birds they were in the spring.

In addition to many adult birds molting, the fall migration includes first-year birds that haven’t attained familiar adult plumage yet. They often resemble females or a mix of male and female plumage.

For the Birds: Plumage challenges of late summer

The Cooper’s hawk I wrote about last week was a bit of an anomaly for me.

It’s not that I don’t see Cooper’s hawks often, but I typically see immature Cooper’s hawks. The one featured last week was an adult. Looking back through my photo collection, the vast majority of Cooper’s hawks I have photographed were immature birds.

With many birds, differentiating young birds from adults can be tricky as the time period between immature plumage and adult plumage is relatively short. With Cooper’s hawks, it’s easier as they retain their immature plumage into their second year. Bald eagles, similarly, do not obtain their classic white heads and tails until they are four or five years old.

As immature birds, Cooper’s hawks (as well as closely related sharp-shinned hawks) are brown with tan-streaked white chests and bellies. As adults, they are blue-gray with reddish-streaked white chests and bellies. Immature Cooper’s hawks have yellow eyes, and adults have red eyes. Interestingly, ospreys are the opposite with adults having yellow eyes and immatures having orange-red eyes.

Hard to beat an American oystercatcher sighting

They aren’t particularly rare, especially if you know where to look, but American oystercatchers are always a thrill to see. I saw these beauties during a short birdwalk at Connecticut Audubon Society Coastal Center at Milford Point the other day. One of the coolest looking birds in New England, if you ask me. Check out the youngster below.

More information about the American oystercatcher may be found here.

For the Birds: This trip up north was a long time in coming

It had been several years since I had been to Pittsburg, NH, a place I used to visit three times a year or more back in the day.

My visits gradually became more infrequent as I got older, gained work and family responsibilities and grew less inclined to make the long drive. Besides, moose sightings had become increasingly rare up there, while they used to be a sure thing. Moose had always been the main attraction for me and many others who visit there.

Even so, the area has retained a special place in my heart, and I often long to be there. I just wish I could teleport there with my truck, canoe and camping equipment.

Warblers up north

Here are a few warblers I saw on my trip up north. Previously, I had posted photos of loons and an eagle. Canada warblers and magnolia warblers are similar looking with their bright yellow chests and bellies streaked with black. There some obvious differences, such as the eyes. Canada warblers have an obvious eye ring, while magnolia warblers have a black mask with less obvious broken eye ring.

For the Birds: Oriole nests are something to behold

Everything about a Baltimore oriole nest is ingenious. From the design and materials to the location selection, the nest is a perfect haven to raise young birds safely from predators (for the most part).

Fall is the best time to find oriole nests, after the leaves have fallen. Of course, by that time, the orioles are long gone, and the nest is a mere relic of the past breeding season, but it’s still interesting to see one of the pouch-like nests dangling from the end of a branch.

The other week, I was lucky enough to watch a female oriole build one of those remarkable nests. I was walking along a trail that was teeming with yellow warblers, catbirds, and Baltimore orioles when I glanced up and saw an oriole perched at the end of a branch overhead.

For the Birds: Blue jays chase owl into the woods

Blue jays give and blue jays take away.

During a walk in the woods the other day, I heard a bunch of blue jays squawking up a storm. It was too loud and frantic to be simple alarm calls for a potential threat. This threat had to be real. The calls and squawks reached a fever pitch as more and more blue jays appeared onto the scene from all directions.

I knew it had to be a hawk or owl that had the jays all riled up. I just had to find it.

After a minute or two of peering into the thick hemlock branches, I noticed a large bird being harassed. The blue jays may have been smaller, but it was at least 15 to 1 in their favor. From my angle, the larger bird was still well hidden. I took a few steps to change my perspective, and my suspicions were confirmed that it was a barred owl.

For the Birds: Icy conditions good for photography, not so much for birds

Every so often in New England, everything is covered in ice. I’m not talking about lakes and rivers freezing or icicles dangling from the edge of roofs. I’m talking about when literally everything outside is covered in ice. Every branch, every leaf, every pine needle, every blade of grass is sheathed in its own covering of ice. 

It doesn’t happen often. Sometimes it’s once or twice a winter. Sometimes it’s once every couple of years. The conditions have to be just right. 

The other week, the conditions were just right. A near-freezing rain fell hard in the evening, and, when the temperature dropped just a bit after the sun went down, it turned into freezing rain. By morning, everything was ice, including a slick covering on the remaining snow.

For the Birds: Flushing a Cooper’s hawk will get the heart pumping

I was walking along a short but windy trail in southern New England the other day in search of overwintering warblers. This short path is known for harboring these tiny songbirds during the winter, as it is adjacent to a water treatment center that features open water on even the coldest days.

I came around one of the many bends and jumped back as I flushed a large bird that was on the ground next to the trail. With my heart racing from the surprise, my immediate reaction was that it was a ruffed grouse. It flushed with the familiar exuberance and noise of a grouse, so my mind immediately went there. Ruffed grouse, however, do not live in that area of New England any longer, and the habitat wasn’t right for the popular game bird.
