Predicting “good” warbler days in spring is tough. Weather to the south and to the north of your locality, along with wind and precipitation combine to make forecasting migration events difficult. Throw in obstacles to time in the field such as work and adulting and Spring migration can be over before it even starts. But, May 2019 started off in great fashion. Southerly winds and a band of precipitation downed birds in an impressive coastal “fallout” in western CT on May 2nd.

A previously discovered Prothonotary Warbler at East Rock Park, New Haven performed well in the morning and it was evident that there were a few more migrants around.

SY male Prothonotary Warbler, East Rock, New Haven, May 2019. A bright bird, with contrast between the yellowish head and green back and grey-blue wings. The olive tinge to the head and slightly browner primary coverts point to a SY rather than AHY male.

AHY female Prothonotary Warbler, Long Point, Ontario, Canada, April 1991 (Julian Hough). Lack of contrast between the head and the mantle (with obvious olive tones) and restrictive yellow on the underparts suggest female. The blue grey primary coverts suggest AHY.

It was also evident that northbound birds were reorienting and dropping into coastal habitat downed by a band of inclement weather. Nick Bonomo had been scouting the coast and discovered the woods at Lighthouse Point Park, on the eastern edge of New Haven was particularly “hot”. So, after work I joined him and spent an enjoyable bird-filled couple of hours. The north woods held an assortment of warblers, down in diversity and numbers from earlier, but there was still more than enough birds to keep my retinas flushed with color! The highlight for myself included two adult male Blackburnian’s feeding at eye level and often watched foraging on the ground.

Ad male Blackburnian Warbler, Lighthouse Point Park, New Haven. Blackish remiges and primary coverts not contrasting with greater coverts age this as a AHY male.

 

AHY male Black and White Warbler, Lighthouse Point Park, New Haven. Good numbers of this amazing looking tree crawler! The black throat and ear coverts sex it as a male and the blackish primary coverts similar in color to the greater coverts make it a AHY

 

Black auriculars and throat sex this as a male. Brownish primary coverts (as opposed to blackish) contrasting with the blackish-centered greater coverts would imply this as SY. Milford, May 2011

Veery, Lighthouse Point Park, New Haven. One of several birds, this one was particularly confiding and was seen in company of Swainson’s and Wood Thrushes.

Chestnut-sided Warbler, East Rock, New Haven. Bright yellow crown and well-marked plumage with extensive chestnut on sides sex it as a male. The slightly browner primary coverts and alula, brownish remiges and slightly worn and pointed tertials and central tail feathers point to a SY male.
