Scoping April

The month of April starts big and ends big! The onslaught of migrants begins in earnest this month.
We start with waterfowl and raptors, move into temperate migrants and then the early arriving Neotropicals! On the second Sunday of the month is the BOS's annual April Bird Census. We always need volunteers to help cover the BOS's vast study area. If you'd like to help, please contact Celeste Morien, the compiler, at [email protected]

This is the best month to spend some time at the local hawk watch in Hamburg. This all-volunteer hawkwatch will have an official counter stationed here daily, unless it's pouring rain. April offers the best diversity for migrating raptors. In addition to highlights of Golden Eagle, Goshawk and Rough-legged Hawk, other species such as diurnal migrant Short-eared Owls, Sandhill Crane, Snow Goose and other rarities have occurred. Pileated Woodpeckers frequently fly through the woods here and this is one of the best spots to cross paths with a Vesper Sparrow during migration.

Iroquois NWR is booming with migrant waterfowl now. Drakes in their full alternate plumage are dazzling to see. Herons and egrets are newly returned and displaying in their rookeries. Osprey are back on their nesting platforms throughout the refuge system. American Bitterns and Virginia Rails will be calling in the marshes. Another gem to be found here is the Black Tern, the last nesting colony in WNY!

Our local migrant hot spots are receiving lots of attention as passerines begin filtering back into town; Hermit Thrush, Brown Thrasher, Ruby-crowned Kinglet, Yellow-bellied Sapsucker. Warm fronts at the end of the month will usher in the first warblers and vireos of the season. Get your hummingbird feeders out as Ruby-throateds and Baltimore Orioles will be looking for fuel. Get your rest! May is up next!


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!

  Reflections on "What the BOS Means to . . . "

. . . Sue Barth

The BOS is filled with helpful, talented, and dedicated people who share their love for birds in so many ways. In my early days (and even now), there were many who kindly offered ID help (and didn't laugh) when I posted my newbie questions to Genesee Birds. Several even took me birding with them, mentoring me, and showing me a much bigger "bird world" than I could ever have imagined. Fast forward to today, I see much of what goes on in the background to collect and prepare all the data that this amazing organization compiles each month and for each count. All in all, I am in awe of the longevity (over 95 years) the society has been around and am awed and grateful to the dedicated people who work tirelessly in the background to make the BOS such a great organization that's knit together by a mutual love for birds!

Field Trip - Batavia Wastewater Treatment Plant with Julia Garver and Sarah Balduf

Details: (click for more info)

5 Treadeasy Ave., Batavia, NY 14020

Sunday, April 20th with a rain date of Monday, April 21st.

Leaders: Julia Garver
(716) 474-1366
email: [email protected]
and Sarah Balduf
(585) 356-2432
email: [email protected]

Meet at the operations center at 830 AM (this is the building you will see in front of you as you drive in through the chain link fence/gate). The facility is located at the end of Industrial Blvd, which is off Pearl St. (Rte 33) at the western edge of the city of Batavia.

Julia and Sarah will lead our group through the famous wastewater treatment plant. This complex of man-made ponds and marshes is a verifiable birding hotspot and has attracted such gems as Northern Wheatear, Harlequin Duck, Piping Plover, Neotropic Cormorant and American Avocet.
While the fall months host most birders at this regional hotspot, the spring migration months are definitely under-birded here. The Purple Martin houses should be filling up with adults returning from wintering grounds in the Amazon. The various settling ponds will likely be playing host to a variety of waterfowl, possibly including Common Loon and Horned Grebe.
If you own a spotting scope, this would be a great location to put it to good use! This will be a 1/2 day trip. Bathrooms are available in the administration building.

Field Trip - Beginner’s Bird Walk at Forest Lawn with Schuyler Lawson and Steve Giamberdino

Details: (click for more info)

Forest Lawn Cemetery, 1990 Main Street, Buffalo, NY 14208

Meet at 9am at the small parking area behind the chapel (see map link above).

Join Schuyler and Steve on a walk through Forest Lawn Cemetery during the spring migration season. We will be looking for early-arrival warblers and other songbirds as they rest and refuel before continuing their journey north. Resident species will be busy singing and nest building. Additionally, we will also be looking for a variety of waterfowl, herons, and Belted kingfisher. Migrating raptors have been known to pass overhead as well so we will keep our eyes to the skies hoping for Broad-winged Hawks.
Bring snacks and water as we will likely be birding for a few hours. Restrooms are not available. Bring binoculars if you have them, we also have a few extra pairs to share.
While this walk is geared towards beginners, all are welcome!

Brooks Pavilion (Main Pavilion), Point Gratiot Park

Leader: Devin Banning (716) 260-8889
[email protected]
Katelyn Davis (716) 216-3881

Meet at 8am at the Brooks Pavilion at Point Gratiot Park. See map link above for exact location. The Brooks Pavilion is the main pavilion inside the park.

Join Devin Banning and Katelyn Davis for a walk through Point Gratiot Park in Dunkirk. The Point serves as a migrant trap and funnels northbound birds into the DEC woodlot, the crown jewel of the park, which offers superb habitat for migratory songbirds. The sandy and rocky shoreline can host migrant shorebirds.
We should see the local Bald Eagles that frequent the lakeshore and we might catch a glimpse of the Peregrine Falcons that nest on the old NRG power plant. The resident Red-headed Woodpeckers are always a treat to see and the Purple Martin houses will be very active. Point Gratiot has hosted some fantastic rarities over the years including Harris’s Sparrow, Worm-eating and Kentucky Warblers, and Summer Tanager.
Birding destinations targeted after we wrap up at Pt. Gratiot will be determined based upon weather and migration patterns on the days leading up to our trip. A stop at the Dunkirk Airport should add a few grassland species to our day’s list including Eastern Meadowlark, Bobolink, American Kestrel and locally-nesting Grasshopper Sparrow.

Leader - Matt Nusstein ([email protected]; (716) 446-3376)

Location - Meet at 8am at the Humphrey Nature Center, 6773 Trailside Road, Castile, NY 14427 (see map link above).

This year’s trip overlaps with World Migratory Bird Day! Scenic Letchworth State Park, embracing the Genesee River, boasts incredible numbers of migratory birds in May and June. In addition, more than twenty species of warblers nest in the park annually making for an exciting birding destination. This list includes the local Louisiana Waterthrush as well as gems like Hooded, Blue-winged and Mourning Warblers. Acadian Flycatcher is another local species we hope to cross paths with during our outing. We will be birding along the gorge making various stops with short hikes as we go. The trip could last 5-6 hours and we will have lunch overlooking the river. Carpooling is suggested. Bring a lunch, snacks and beverages.

Field Trip - Joseph Davis State Park with Dave Spiering

Details: (click for more info)

4143 Lower River Road, Youngstown, NY 14174

Sunday, May 11, 2025

Leader is Dave Spiering (716) 548-6846
email: [email protected]

This will be a 1/2 day trip starting at 8:00am. Meet at the central parking lot in the middle of the park - see google map link above.

Joseph Davis State Park includes the Joseph Davis Bird Conservation Area (BCA). The BCA is over 200-acres of successional shrubland, mature second growth forests, old fields, wetlands, and ponds managed for bird habitat, primarily birds that prefer open and early successional habitats. In the past, Parks and other partners (USFWS, Audubon) have managed the BCA to maintain open and early successional habitats and Parks will be doing similar work at Joseph Davis in the coming years. We will bird the eastern side of the park in the BCA looking for spring migrants and species that will stay to nest. Parks asks for your assistance to make an eBird list while birding at Joe Davis to help us monitor and manage the BCA for the best bird habitat possible. JDSP has recently seen improvements to the parking areas, access roads and trails.
Based on eBird checklist entries, this park is very much under-birded. Part of the motivation behind David leading this trip is to spark more interest in future bird outings to this state park! There are many gaps in the eBird data for this location so your participation in this event, besides enjoying a May morning of birding out with your friends, has legit scientific value!
