Birdathon 2025 - What We Discovered

By Kyle Bardwell - May 17, 2025

On May 17th , 2025 Putnam Highlands Audubon Society (PHAS) held its annual Birdathon fundraiser. Like many Audubon’s and other bird groups around the country, PHAS hosts a Birdathon to help fundraise for conservation and protection. It involves a 24-hour window for participants/teams to count as many species as possible. People pledge money based on number of species seen to donate to the cause of conservation and protecting bird habitat.

This year, board members split into two teams. I was a member of one of the teams, named the ‘diabolical nightjars’, in which we birded from 4AM-9PM, staying within the boundaries of Putnam County. The other team, historically named the ‘Garrison Gumshoes’ traversed slightly farther and ventured into other counties, including Rockland and Sullivan County. The 17-hour day was tiring, but easy compared to last year’s all out 22-hour day.

Although the Birdathon was less extensive than last year, in total over 120 species of birds were tallied by the groups, with some phenomenal sightings. The diabolical nightjars put themselves to the test with the limited range of solely Putnam County. The small County is lush with birds, but lacks coastal habitat, has less options for migrant hotspots, and shorebird/grassland habitat. It was fun to put everything we know about Putnam birding into a 17-hour day long birding event. We traversed all of our favorite spots finding some great things along the way.

Many of the places were visited are regular spots for our monthly bird walks including Hubbard Preserve, Glynwood Farm, Little Stony Point, Constitution Marsh, and Fahnestock State Park. It was a full circle moment, in the fact that we bird all of these local spots year around, however have never challenged ourselves to hit them in one- day to see how many species we could get. It was an exercise of all of our knowledge inclusive of small tips and tricks that we learned from Putnam birders long before our time.

We had some great moments on the Birdathon that really made the day worth it. At one point in the morning we got hit with a quick and aggressive rainstorm. We drove through the rain, in hopes the storm dropped some migrating birds onto the Hudson River. We arrived at Cold Spring Gazebo and quickly got on a large migrating flock of Brant. This waterfowl/goose species spends its winter in coastal habitats and migrates back to nest on the northern tundra. Sometimes this species will make a short cut and fly directly north up the Hudson River, which we were lucky enough to see right after the rainstorm.

Another great moment on the count, was when we travelled east in search of a black crowned night heron. It was a particularly difficult bird to pull out, but we did, and got lucky with some awesome sightings to go with it. 

Just after seeing the heron, Sean looked into the sky and picked out a large migrating flock of brant, migrating North, far from any known flyway such as the Hudson River. At the same time Sean picked up multiple common nighthawks migrating north as well. The common nighthawk is not as common as the name seems. It is a nightjar (nocturnal) species, that has a very unique looking face, and has a unique flight style as it hunts insects. They can be almost completely camouflaged when perched on a tree branch. This was a fun addition to the day’s list.

All in all, it was a great birdathon with a lot of fun stories and great birds.
