Fall Bird Migration in Connecticut

A shoreline state where hawks reluctant to cross Long Island Sound pile up along the coast: the state agency points to the daily count at Lighthouse Point Park in New Haven and the broad-winged hawk movement over Quaker Ridge in Greenwich in September.

Public viewing sites in Connecticut

Every place below is one an agency itself describes for watching the fall passage, with the agency named and linked, the species it documents there, the months it names as the peak, and the facility that exists: a tour route, a platform, a tower, a visitor centre. Where the agency wrote a sentence worth reading, it is quoted exactly.

DEEP's magazine describes the park as one of the premier locations in southern New England for observing migrating hawks, eagles and falcons, with official counters stationed every day from September 1 until November 30, starting at 7 a.m. and continuing as long as the hawks keep flying, who help visitors spot and identify birds. The HawkCount profile says counts are made from the southernmost parking lot and that the park has parking, picnic areas and beaches; sharp-shinned and broad-winged hawks are among the species tallied.

“It is one of the premier locations in southern New England for observing migrating hawks, eagles, and falcons, as well as a variety of songbirds.”

DEEP's magazine says the season runs from August 20 to November 20, seven days a week, with an experienced hawk watcher on hand to answer questions, and calls the ridge a great location to observe the mass movement of broad-winged hawks through Connecticut, mostly in September. The HawkCount profile says hawks have been counted here since 1972, that a paid watcher covers weekdays and volunteers the weekends, and that visitors can park directly next to the hawk watch lawn, which makes the site accessible to wheelchairs and walkers.

The coloured grid is where people have uploaded a verified sandhill crane record to iNaturalist in September, October, November and December, brighter where more have been logged. It is a map of reports rather than of birds: it thickens around refuges, car parks and towns because that is where observers stand, and it shows past reports rather than birds present today. Pins are public viewing sites an agency itself describes; grey dots are US Fish and Wildlife Service refuges and hatcheries, drawn because the refuge system is where most of the staging happens.

When

When the passage peaks in Connecticut

Connecticut DEEP, Connecticut Wildlife magazine, September/October 2010 puts the Connecticut peak at September for the broad-winged hawk movement, with the coastal count at Lighthouse Point running September 1 through November 30. That describes a pattern across past autumns. The week itself swings with the weather: a cold front to the north moves cranes and geese south in a single night, and a warm spell holds them for weeks. Dawn and the last hour before dusk are when cranes and geese move between the fields and the water, and that movement is the spectacle the platforms are built for.

Connecticut's fall migration is shaped by Long Island Sound. DEEP's own explanation is that falling temperatures behind a cold front stimulate birds to move, north to northwest winds push them toward the Atlantic coast, and many hawks are reluctant to cross open water, so they concentrate along the shore and follow it south and west until they pass over places like Lighthouse Point Park in New Haven and Cape May in New Jersey. The agency names Lighthouse Point and Quaker Ridge as the state's notable hawk watches, points readers to HawkCount for directions to all of them, and describes a daily count at Lighthouse Point from September 1 to November 30. No agency names a goose or swan staging site in the state.

Below, one curve per species the agencies document in Connecticut: every research grade observation members of the public have uploaded to iNaturalist for the state, by calendar month across every year the platform holds, with September to December shaded. Counts of uploads, so they measure observers as well as birds, and the shape is worth reading where the absolute numbers are not.

Broad-winged hawk

186 research grade broad-winged hawks observations have been uploaded to iNaturalist for Connecticut across every year the platform holds, and 22 percent of them fall in the four shaded autumn months. The busiest month in the record is May. An autumn month carries about 0.55 times as many uploads as an average month outside autumn. People upload most of everything in July, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Sharp-shinned hawk

216 research grade sharp-shinned hawks observations have been uploaded to iNaturalist for Connecticut across every year the platform holds, and 61 percent of them fall in the four shaded autumn months. The busiest month in the record is October. An autumn month carries about 3.08 times as many uploads as an average month outside autumn. People upload most of everything in July, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Latest reports

What people have reported in Connecticut lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Connecticut, as a date and the platform’s own coarse locality. Evidence that people do find broad-winged hawk and sharp-shinned hawk here. Each is one bird on one past day: the flocks move with the weather, so where they are this week is what the agency page and its counts answer.
