Annual Birdathon

Team Baldpate's happy birders with Birdathon leader Tyler Christensen at Baldpate, May 2016
Team Baldpate with leader Tyler Christensen finished with 76 species. Highlights included 19 species of warblers, several Swainson’s Thrushes, and an amazing show put on by a pair of Yellow-billed Cuckoos. Check out these happy birders!

Birdathon ’19 is just around the corner—Saturday, May 11th!

Join us at the height of spring migration on International Migratory Bird Day, Saturday May 11 (rain date is May 12.). Our only fundraiser of the year brings together people who love birds and the environment for a friendly competition to spot as many species as possible during that day. Everyone is invited to join one of the WCAS-guided walks. You do not need to be an expert birder to participate. Beginners are welcome.

For a great cause

Birdathon proceeds make it possible for WCAS to continue our local educational outreach, research and conservation efforts. They help further our understanding of both our year-round resident and migrating bird species and enable us to share birding insights and knowledge in a variety of community programs. WCAS also supports the research efforts of Hannah Suthers at the Featherbed Lane Bird Banding and Research Station and Tyler Christensen’s Northern Saw-whet Owl monitoring program in Mercer County with purchases of essential research equipment and birding gear supported by your generosity.

Birdathon Blackburnian
Team Baldpate led by Tyler Christensen (left) found a male Blackburnian Warbler like this one!


On May 12, 2018, twelve teams of intrepid birders braved the threat of rain and went out to count birds for Birdathon ’18 in a variety of places and habitats. Areas covered included sites in the Sourlands (Baldpate, Hollystone , Fiddler’s Creek by Sharyn and Tyler, Amwell Lake, Omick Woods, Cedar Ridge Preserve by Juanita) and the Featherbed Lane banding station at Sommer Park Preserve (Hannah); the Pole Farm (Fairfax); Brig and Tuckerton (Brad); Institute Woods (the Spars); Assunpink (John Maret and Team Beck); South Branch WMA and Skillman area (the Youngs); parts of Plainsboro, Montgomery and the Griggstown Grasslands (Barbara and Tom); Duke Farms (Tim Brown); Bull’s Island, Bowman’s Hill and Lambertville area (Franta); Curliss Lake Woods (Mark Witmer).

A total of 161 species was seen by those who submitted lists, including 27 warblers and a yellow-breasted chat. Five species were seen by everyonethose were Red-bellied Woodpecker, Northern Flicker, Blue Jay, Am. Robin and Gray Catbird. Another seven species appeared on all but one list (not always the same one list) – Great Crested Flycatcher, Wood Thrush, Common Yellowthroat, Song Sparrow, N. Cardinal, Red-winged Blackbird and Brown-headed Cowbird.

Six of the twelve lists featured at least one of 51 unique species (i.e., not reported by any others). I had one (Broad-winged Hawk, nesting near my house), as did Mark Witmer (Solitary Sandpiper). Fairfax Hutter had three (Blue Grosbeak, Grasshopper Sparrow and Least Flycatcher), Sharyn Magee and Tyler Christensen had four (Hooded Warbler, Kentucky Warbler, Alder Flycatcher, Yellow-billed Cuckoo).   John Maret had five (Yellow-breasted Chat, Ruddy Duck, Pine Warbler, Belted Kingfisher and Common Loon). Franta Broulik had eight (Common Merganser, Common Raven, Purple Finch, Wilson’s Warbler, Yellow-throated Warbler, Cliff Swallow, Common Nighthawk and Barred Owl). Brad Merritt claimed the remaining 29 unique species, a wonderful selection of shore and water birds.

The leaders of the top three teams in terms of total number of species tallied were:

1) John Maret (95)     2) Brad Merritt (89) 3) Franta Broulik (87)

SPECIAL SECTION – Icelandic bird list

Andrew Bobe submitted the following list of unique birds. While he was in not able to be in the NJ/PA area on Birdathon Day, he was still counting!

Graylag Goose, Whooper Swan, Rock Ptarmigan, Eurasian Shag, Common Snipe, Common Redshank, Eurasian Oystercatcher, Lesser Black-backed Gull, Great Skua, Redwing, White Wagtail, Eurasian Blackbird.

Great job, everyone!
