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 Celeste.morien@gmail.com

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!

Details: (click for more info)

Saturday, April 24th

Meet at 9:30 AM in the parking lot at Braddock Bay State Park, 199 E Manitou Road, 14468.

David Gordon (dgordonphoto@yahoo.com; (716) 390-1429) leads this trip.

Weather permitting, we will indulge in the spectacle of spring hawk migration from the hawkwatch platform. The bay should also have good numbers of waterfowl and the nearby woods may hold new arrival passerines. If owls are present, a short trip to Owl Woods will also enliven the day!

This is a full day trip so bring drinks, lunch, snacks, sunscreen and a chair (for hawk watching). Bathrooms are likely available at the park. Be aware that a lake breeze can develop this time of year which is a cool/cold breeze out of the north compliments of Lake Ontario. Dress appropriately.

Field Trip - Montezuma NWR

Details: (click for more info)

Leader is Christopher Bertola; chris.bertola10@gmail.com

This trip is new to the BOS field trip menu, and what a great addition it is! The Montezuma National Wildlife Refuge complex is a massive wetland that occupies 15 square miles at the north end of Cayuga Lake. Please join Christopher Bertola as we explore this unique hotspot and work on building your Seneca County life list.

This vast area is a critical stopover site for many migrants and at this time of year, we will be looking for various waterfowl, including rarities like Eurasian Wigeon and Ross's Goose, and early arriving shorebirds such as Pectoral Sandpipers and Dunlin.

Most of this trip will take place along the Wildlife Drive with frequent stops to scan flocks of ducks. Bring your scope if you have one! Marsh Wrens should be singing from the cattails as Black Terns bound across the open waterways in search of insects and minnows.

If any rarities have been found recently, we will try for those as well. With 267 species recorded along the drivable berm alone, something stand-out is bound to await us! This trip is anticipated to wrap up around 1pm. Plan to bring a lunch/snacks and beverages. Bathrooms are available at the visitor center.


May 01, 2021   (Saturday)

Field Trip - Tifft Nature Preserve

Details: (click for more info)

Meet at 7:30am on the bridge just past the Visitor Center.

Leader: Seaghan Coleman (716-435-7753 or seaghanc@gmail.com)

This trip will focus on newly arrived neotropical migrants as well as lingering waterfowl and sparrows. Tifft holds the distinctive honor of having the highest number of species recorded on premises in our region - over 250! The list of highlights is long and includes Kentucky, Connecticut and Yellow-throated Warblers, Summer Tanager, Sedge Wren, Barn Owl, Yellow-crowned Night-Heron and so much more.

We will hike the trails in search of early-arriving warblers, thrushes and other long-distance migrants as well as look over the marsh for rails and bitterns. If we are lucky, we may see late migrant raptors.

This will be an easy walk over level ground and boardwalks, possibly muddy trails. The trip will span the morning hours so make sure to bring snacks and something to drink.

We will focus on seeing the locally rare Upland Sandpiper and Grasshopper Sparrow. These species nest in the grassland portion of the preserve. Other species of interest include Bobolink, American Kestrel and Eastern Meadowlark.

We will also take a walk through the wooded portion of the preserve for neotropical migrants. The wetlands host Sora and Virginia Rail, both of which have nested here in previous years. Bring bug repellent for the mosquitoes! Our trip will commence from the parking lot as we explore the southern area of the preserve, including the marsh, and then the group will relocate to the northern end to finish our trip.

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.
Plan on a half-day trip focused on Neotropical migrants during the peak of avian diversity movement through our region. Photo of a male Cape May Warbler from Amherst SP by A. John Ryan 5/18/20.
