V O L U M E 6 9 ( 2 0 1 6 ) • N U M B E R S 3 / 4 371 H U D S O N - D E L AWA R E and 3 over Glassboro, Gloucester 24 Jun (Mi- chael Pasquarello). None were reported in New York or Delaware. A Swallow-tailed Kite over Gordon's Pond, Henlopen, DE 24 Jul was unseasonable (ph. Chris Stanger); most appear in spring. Absent from Long Island as breeders since 1930, Bald Eagles nested on Gardiner's Is - land, at the e. end, in 2006. Four additional sites are now occupied: Wertheim N.W.R., Mashomack Preserve, Bayard Cutting Arbo - retum, and the William Floyd Estate, all in Suffolk. One killed by a car in Monroe, NY in June was 38 years old, the oldest on record by five years. The cold wet spring aborted some Bald Eagle nests in New Jersey, but 150 active pairs, up from 146 last year, still fledged 200 young. (KC). Delaware had 90 Bald Eagle ter - ritories and 68 active pairs that fledged 85 chicks, slightly above last year (Kate Flem - ing, D.N.R.E.C.). A Northern Harrier with 3 dependent young at Freetown Corners, Cor - tland, NY constituted the southernmost con- firmed breeding, although there was sugges- tive behavior on Long Island, where harriers bred commonly 20 years ago: a male carried something at Jones Beach 12-13 Jul (Ardith Bondi, BA), and a pair was seen engaged in apparent prey exchange 12 Jun on Plum Is - land, off the e. end of Long Island (John Sepe- noski). Individuals are still reported to eBird in appropriate habitat all the way south to Delaware. Sandhill Crane, breeding in New York since 2003, raised young at Montezuma and Oak Orchard W.M.A., Genesee (Celeste Morien), but 2 young at Honeoye Creek W.M.A., On - tario (Kathy Kirsch) were considered year- lings. A pair appeared resident at Catherine Creek, Schuyler (JMcG, LS, Ian Davies). Tran - sients visited all three states. SHOREBIRDS THROUGH SKUAS A Wilson's Plover at Stone Harbor Point, Cape May, NJ 22 Jul (TR) was the second there air, CD). They were above the mean/median at Pea Patch, with 171. Two Yellow-crowned Night-Heron nests on Governor's Island, New York Harbor (Gabriel Willow, m.ob.) add a new urban nesting site to the lengthening list. The continuing Redfern Houses colony in Queens had 50 nests, and there were 10 else - where in New York Harbor (TW). A colony of 17 at Cammann's Pond, Merrick, Nassau, NY (Amy Simmons) seems to be new. A Glossy Ibis was far afield at Perch River 12 Jun (Jim Tarolli). Glossy Ibis declined by 55% from last year in New York Harbor, to 79 nesting pairs (SE, TW). Pea Patch had an encouraging 655 individuals 24 Jun (CB). A White-faced Ibis at Captree S.P., Nassau, NY 18 Jun (Arie Gilbert) through at least mid-Jul was the second there in two years. A late spring hawk transit along Lake Ontario, now expected, brought 360 Broad- winged Hawks, a Red-tailed Hawk, 10 Bald Eagles, 12 Turkey Vultures, and a possible Black Vulture past Braddock Bay 4 Jun (Mike Tetlow). A Mississippi Kite settled at Ware - town, Ocean, NJ from about 16 May until late Jul, and although a second bird was reported, no nest or young were observed (Eileen Ben - nett, m.ob.). Other New Jersey sightings were fleeting, including two observations of what was perhaps the same bird in Monmouth 10 Jun, over Middletown (John & Dena Temple) and over Hazlet/Keyport (Larry Scacchetti), 290 out, mostly Black-crowned Night-Her- ons), the best total in recent years. All spe- cies except Snowy Egret and Yellow-crowned Night-Heron were above the mean/median there (CB). A helicopter count in late May of New Jersey heronries by N.J.D.F.W. reported approximately 4133 individuals of seven spe - cies (CD), a bit above last year. A total of 183 Great Blue Herons were counted at Pea Patch, the only place in the Region where they nest near the coast. Great Egrets slipped slightly to 381 nests in New York Harbor and to 1316 individuals cen - sused aerially in 20 New Jersey colonies, but the count of 389 at Pea Patch was above the mean/median. Snowy Egrets were up to 273 pairs in New York Harbor, 1109 were noted from the air in 19 colonies in New Jersey, and only at Pea Patch were they slightly below the mean/median at 93. Two imm. Little Blue Herons wandered to Richfield Springs, Herkimer, NY 21-23 Jul (Louise Gomez, Lynne Canderwater, Kevin McGann, BP). Elsewhere, only six pairs nest - ed in New York Harbor and only 58 individu- als were censused in New Jersey, but 421 at Pea Patch showed a healthy increase there. Tricolored Herons continue to dwindle. New York Harbor had only two nests, and only 36 individuals in 11 colonies were censused from the air in New Jersey. None have been counted in Jun at Pea Patch since 2011. Three at Bombay Hook 20 Jul+ (Gina Sheridan et al.) and 3 at the Port Penn, New Castle, DE impoundments 25 Jul+ (AK, TS) were prob - ably in post-breeding dispersal. Only one Cattle Egret was reported in New York, at Ja - maica Bay 30 Jul (Rich Kelly) and only one in n. New Jersey: De Korte Park, Bergen 8 Jul (John Collins, Carol Resch). A count of 580 at Pea Patch 24 Jun, however, was far above the mean (CB). Black-crowned Night-Heron tallies shrank to 550 pairs in New York Harbor, though they remain the most numerous heron species there. The New Jersey aerial survey counted 356 individuals in 27 colonies, probably un - dercounted (dark birds are less visible from the SA After their near-absence last summer, White Ibis moved northward in one of their greatest recorded irruptions. First came a second-year bird at Ocean City, Cape May, NJ 22 Jun (ph. Brian Kushner), possibly present several days earlier. In Jul, they flooded into coastal Delaware, the largest concentration being a roost near Lewes, Sus- sex, at the mouth of the Delaware River, that peaked at 111 on 23 Jul (SG). Curiously, only a few crossed into New Jersey. The most northerly of these were 2 on the Delaware River at Fort Mott, Salem 22 Jul (David Weber, fide SK) and one coastally at Brig 28 Jul (Ernst Hahn). All were first-cycle birds except for 2 largely white second-cycle birds: the aforementioned Ocean City pioneer and another at Stone Harbor, Cape May, NJ in early Jul (Bert Filemyer, fide APE). New York surprisingly had none. SA Ospreys have recovered their pre-DDT numbers, but they are distributed differ- ently. In New York, Ospreys now nest more generally throughout the state. On Long Island, Ospreys were traditionally limited to the east end, where Gardiner's Island housed over 300 pairs and nearby Plum Island 250, some with huge ground nests. Now Ospreys nest w. on Long Island into New York City at Jamaica Bay, where a record 21 nests produced 45 young (DR). On 14 Jul Gardiner's Island had 37 nests containing 51 young MS). Ospreys remain curiously absent from the Hudson Valley. None nest in Or- ange (Ken McDermott) or Dutchess, NY, though a few were present in the latter county (Barbara Butler, Stan DeOrsey). Two pairs nested successfully in Ulster for the first time, at Lloyd and Kingston (Nancy Ebel, MB). In New Jersey, the 28 Jun storm killed some Osprey chicks, but the state now has an estimated 600 pairs, and the 423 nests studied closely had a good productivity rate of 1.75 young per active pair (KC). We have no to- tals for New York or Delaware.
