For the Birds: The shore comes through again

The spring migration has certainly begun, but it is still in the building-up phase.

I took a few walks in the woods over the last few days and saw some very welcomed migrants, such as pine warbler, palm warbler, yellow-rumped warbler and Louisiana waterthrush. 

When migration is just picking up, however, the action can be hit or miss. In a few weeks, the action will be all hits all the time, and I’m sure we are all looking forward to that.

While those first migrants are great to see after a long winter, they also whet the appetite to see more spring migrants. The woods will be hit or miss for the next several days anyway, so the other day I went to a spot where I knew I would see a few old feathered friends that I hadn’t seen since last summer.

The coast, whether it is the Atlantic Ocean, one of its many bays in New England, or Long Island Sound, is a safe place to find some early shorebird migrants in April. I had a little time, so I headed for one of my favorite spots along the Long Island Sound shoreline in southwestern Connecticut. The spot, the Coastal Center at Milford Point, rarely disappoints, and this time, it was certainly on the mark again.

In terms of sheer numbers and variety, the action was OK, but in terms of quality, it was a well worthwhile trip. One side of the sanctuary is a large tidal bay, and I immediately spotted an osprey pair on its usual nesting platform, as well as dozens of brant and a sizable number of green-winged teal.

The other side of the sanctuary, which features a long sand spit and the whole of Long Island Sound, is where the real action takes place in April, as piping plovers and American oystercatchers return to their breeding grounds. 

Last year, I made a similar trip a little later in April and was lucky enough to find a piping plover mother with two chicks following closely behind. This year, by chance, I timed it to coincide with the mating season and saw several males displaying and chasing females, and even caught one pair in copulation.

It was good to see the breeding activity, as piping plovers are a species in decline. The Cornell Lab of Ornithology has a paragraph on its website explaining the conservation status as such: “The 2025 State of the Birds report lists Piping Plover as an Orange Alert Tipping Point species, meaning that it has lost more than 50% of its population in the past 50 years and has shown accelerated declines within the past decade. Partners in Flight estimates a global breeding population of 8,400 individuals and rates the species a 16 out of 20 on the Continental Concern Score.”

The sand spit offers a good opportunity to get relatively close to piping plovers. The area where nesting activity occurs is generously roped off to give the birds plenty of space to do their thing. 

There were several pairs of oystercatchers as well. Oystercatchers, with their large size, massive orange bills and ubiquitous high-pitched call, are consistently on my ever-changing list of favorite birds. 

Given the choice, I would pick the woods over the shore almost every time. The shore, however, does call to me on occasion, and I’m always glad when I hearken to the call.

For the Birds: Winter finches starting to come around

I wrote about the winter finch forecast a few weeks ago. The annual forecast predicts which and how many finches will irrupt into New England from the north each winter. An irruption occurs when birds that are not typically seen in an area appear, sometimes in great numbers, during the winter.

Food, of course, is the main driver of these irruptions. If the seeds of a bird species’ diet are scarce up north, the birds will come south to find a food source.

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.

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.

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.
