Scoping May

It's showtime! This is the month we have all been waiting for! The possibilities are endless. The beauty of May is that you can basically go birding anywhere and expect to see migrants. The birds arrive in pulses, usually accompanying a warm front. On the third Sunday of the month is the annual May Bird Census. Please join us by volunteering some of your time on this day! This year's compiler is Bob DeLeon, please contact him if you can assist with the count at rldeleon@yahoo.com.

There is an art to birding in May. Weather plays a huge part on when birds arrive and where they make landfall. Generally speaking, locations along the immediate lakeshores can sometimes be loaded with birds. This is most likely to happen after the passage of a warm front followed by a cold front resulting in rain. The precipitation can ground birds and produce fallout conditions. Of course the planets have to align in order for a fallout to occur, but when it does, it's magnificent!

The traditional migrant hotspots are the popular focus in May: Forest Lawn Cemetery, Tifft Nature Preserve, Reinstein Woods, Goat Island, Four Mile Creek State Park and Fort Niagara State Park. On years with cooler weather, leaf bud is delayed the closer you are to the lake shores. Inland locations will tend to leaf out earlier and therefore be more attractive to migrants. Forest Lawn Cemetery is widely acclaimed as a spring destination for Neotropical migrants. This is due to its inland location resulting in earlier leaf out as well as its oasis-like appeal to birds looking for a resting place after a long night of migration. The list of rarities located here is long. Unfortunately, migrants this time of year don't tend to linger. These birds are on a race to get back to their breeding grounds.

May still offers hawk flights at the Hamburg Hawkwatch. By this stage of the spring raptor migration, immature Broad-winged Hawks make up the bulk of the numbers as well as young Bald Eagles and Sharp-shinned Hawks. In the early mornings at the hawkwatch site, you can test your skills at identifying overhead passerines. These birds are dispersing inland away from the lakeshore to find suitable foraging habitat for the day.

WNY is not known as a great spring shorebird site, but they do pass through the region in May. The traditional locations are the best area to check: Woodlawn Beach SP, Batavia WWTP and Iroquois NWR. Also worth checking are the farm fields in Niagara and Orleans Counties - especially after a heavy rain. Not only does the rain create temporary mud puddles in agricultural fields for the shorebirds to forage in, but precip events will also ground the birds during their overhead passage. One of the most stunning sandpipers to cross paths with this time of year is the Dunlin. Species such as Solitary and Spotted Sandpipers can be found along creeks and pond edges at Forest Lawn Cemetery, Reinstein Woods and Delaware Park Lake.

Later migrants are still sifting through towards the end of the month, species such as Yellow-bellied and Olive-sided Flycatchers, Mourning and Blackpoll Warblers and Gray-cheeked Thrush.

Memorial Day weekend is the traditional time to look for migrant Whimbrel along the Fort Erie Lakeshore just west of the Peace Bridge. Most Whimbrel migrating through the region cross the fetch of Lake Ontario and there is a watch set up near Toronto to record the thousand-plus birds that pass through annually, all within a few short days. Every year a few birds end up along the rocky shoreline of Fort Erie. Check the end of Kraft Road, Windmill Point and Rock Point Provincial Park. The breakwalls along the Buffalo Outer Harbor would also be worth scoping.


The Buffalo Ornithological Society, Inc. (BOS) was established in 1929 to promote the study of the birds of the Niagara Frontier Region. Annual grants are awarded by the BOS to fund member-sponsored avian research projects. We are proud of our extensive scientific research databases, our continuing involvement in environmental and conservation activities that impact birds, and our promotion of the enjoyment of ornithology.

The BOS coverage area includes Western New York and parts of nearby Ontario, Canada. This region is rich in bird life with over 380 species and 25 recognizable subspecies of birds recorded. Explore our site to learn more about where to report and find birds, both regional specialties and rare visitors.

The Buffalo Ornithological Society has something to offer to anyone passionate about birds: from the backyard feeder- watcher, the avid lister or the environmental activist, to the dedicated citizen scientist or the professional ornithologist. Society activities include regular programs, field trips, intensive long-term bird counts, checklist and date guide development, varied research activities, and involvement in local conservation efforts. We invite you to join in the activities of the society!

May 15, 2021   (Saturday)

Field Trip - Amherst State Park

Details: (click for more info)

Leader: Christina Rockwell Rockwell.christina@gmail.com (302) 530-9480

Meet at 7:30am in the parking lot located on the south side of St. Mary’s Apartments. This will be a 1/2 day trip wrapping up around 11am.

Please join Chris as she guides us through one of the premier migration hotspots in WNY. This easily walkable park is a pleasure to stroll through and can be very birdy. Last spring, gems like Worm-eating Warbler and Sedge Wren were recorded here. The eBird checklist for this location currently stands at 199 species and wouldn’t it be fun to hit the 200 species milestone on Chris’s trip?!
The list of rarities found here over the years include Western and Summer Tanagers, Nelson’s Sparrow, Worm-eating and Connecticut Warblers...even Long-eared Owls nested here one year! Late spring flights of Broad-winged Hawks occur when the winds are out of the SW.

BOS May Bird Count

Details: (click for more info)

All BOS members should participate in the 83rd annual May Bird Count.

BOS members are encouraged to participate. Please help us add to the decades of records that the BOS has collected reflecting population dynamics of the area birdlife. You can be part of a field team or simply count birds at your backyard feeder. All observations are important! If you don't know what section you live in, please contact Bob DeLeon who will put you into contact with the correct section compiler. Please visit the May Count information page on the website at the address below. Thank you so much!
