Plan Your Weekend: The Garden’s Annual Bird Count

Posted in Learning Experiences, Programs and Events, Wildlife on December 12 2008, by Plant Talk

Here’s What You May See on the Tally

Debbie Becker leads a free bird walk at the Garden every Saturday from 11 a.m. to 12:30 p.m., beginning at the Reflecting Pool in the Leon Levy Visitor Center. Join her tomorrow, December 13, for the 2008 New York Botanical Garden Bird Count.

Northern CardinalEvery year at this time, birders flock to the parks and woods across the country and beyond for National Audubon Society’s annual Christmas Bird Count. From dawn’s early light until dusk birders count all the birds they can find using a specific method and within precise geographic areas. At the end of the day the counts are tallied and compared to numbers from previous years. The information is used to determine if a bird species is in trouble or declining. Past revelations included lower than usual numbers of house finches, most likely due to conjunctivitis, and decimated crow numbers, presumably due to West Nile Virus. Occasionally, a rarity will pop up on the count as birders scour the shorelines, forests, and meadows looking for elusive visitors to their areas. Past special sightings at the Botanical Garden, which is part of Audubon’s 84-year-old Bronx-Westchester count, include common redpolls, chipping sparrows, pine warblers, Baltimore orioles, and a merlin.

Twenty years ago I started the Garden’s own unofficial bird count, a low-keyed version that is fun and educational. Instead of gathering at 5 a.m., we meet at 11 a.m. and set out to count the birds at NYBG. I keep a list of the most common New York City birds and put strokes near their names as we spot them flying by. The two decades of data from our informal count confirms the trends found in the Audubon count.

Read about the birds likely to be found on the count and of a special sighting last year after the jump.

UPDATE 12/18/08: Bird walk results

Count day was sunny and cold, with temperatures in the 20s. Nineteen people participated; the count lasted three hours and turned up 24 species and 105 birds overall. Highlights of the day included a northern shoveler at Twin Lakes, both the female and male great horned owls in the Forest, and a goshawk, for the second year in a row, by the Prop Range. A flock of house finches, a brown creeper, and a house wren also were good finds. The full list is noted here.

Plan Your Weekend: Free Bird-watching Walk

Fall Brings an Array of Migrants

Debbie Becker leads a free bird walk at the Garden every Saturday from 11 a.m. to 12:30 p.m., beginning at the Reflecting Pool in the Leon Levy Visitor Center.

Red Tailed HawkAutumn is that miraculous time of year when the leaves on the trees turn glorious colors. It is also time for the great fall migration. From August through November, thousands of birds leave their northern breeding grounds and return to their southern homes. As they pass through NYBG they stop and eat the luscious crab apples, berries, and nuts emerging from trees, bushes, and shrubs. It is a unique time of year to see tanagers, orioles, grosbeaks, and warblers in different stages of maturity as they move through the area.

Also migrating are raptors. Red-tailed hawks, red-shouldered hawks, kestrels, Cooper’s hawks, and sharp-shinned hawks are just some of the accipiters and buteos that glide on the thermals over Daffodil Hill. More than 5,000 broad-winged hawks have been spotted in one afternoon at NYBG. Bald eagles and golden eagles fly lazily over the Bronx River searching for a meal. Osprey circle above as they, too, fish the Bronx River.

White-throated SparrowOn Twin Lakes, the wood ducks and mallards emerge from their state of eclipse and reclaim the lakes in full-colored feathers again. Joining them are autumn migrants: gadwalls, green-winged and blue-winged teals, northern shovelers, hooded and common mergansers, buffleheads grebes, coots, and many surprise visitors.

During October, the Garden plays host to a wide variety of sparrows: tree, field, savannah, song, swamp, fox, chipping, white-crowned, white-throated, and more. November brings the grackles and the blackbirds migrating in the thousands. Large flocks will sweep over NYBG and literally turn the trees black when they perch, all the while cackling loudly.

As autumn comes to an end during the middle of December, our great-horned owls begin to stir. Their breeding season will be just beginning as they emerge from the forest ready to entertain us with mating calls and rituals.

Autumn at NYBG is an exciting season. Come join us on a fall bird walk. You never know what or “hooo” you will see.
