MA - Mourning Warbler.....Northfield

 

Mourning Warbler - Caldwell Road, Northfield, Franklin Co., MA. September 14th, 2021.

The last two days have seen a distinct swing towards slightly later season migrants in Northfield with Swainson's Thrush, Northern Waterthrush, Yellow-rumped Warbler and White-throated Sparrow (8) all making their first appearances at Caldwell Road fields. In addition, up to 25 Common Yellowthroats and 5 Lincoln's Sparrows both showed obvious increases over the 13th and 14th. A couple of late migrants also turned up with two Yellow Warblers (together) and a Willow Flycatcher on the 13th.

But in general, warbler numbers and diversity remain quite low for this time of year. All the more rewarding then to have good views of a calling Mourning Warbler on the 14th, in my view something of a county rarity on fall migration. In fact, I've actually had more luck with Connecticut Warbler over the years though the tiny handful of Mourning Warblers I've encountered tended to be bolder and more cooperative.

The 14th also produced a 'heard-only' Connecticut Warbler that called just once from a dense patch of Jewelweed, totally catching me off guard as I walked a mere five paces from my car at the start of the day. Despite much effort and patience, it couldn't be coaxed into view. While I'm pretty hesitant to call Connecticut Warbler by sound only the loud, distinct 'pwik' call was close enough to be sure and I'm not at all surprised that the bird didn't show given the mercurial nature of the species. 

May 6th -

White-crowned Sparrow - Barton Cove, Gill, Franklin Co., MA. May 6th, 2020.

Another chilly start to the day, even colder than yesterday morning with a sharp frost in Gill and dawn temperatures of around 29 deg F. Barton Cove again proved attractive to swallows with at least 4 Cliff and 25 Bank Swallows hawking over the water. The riverside vegetation had some interesting migrants including at least 5 Northern Parulas, several Yellow-rumped Warblers, 15 White-throated Sparrows and a crisp adult White-crowned Sparrow, the latter hot on the heels of one in Deerfield on the 4th and 5th (David Sibley). Throughout the morning Wood Thrushes could be heard singing at every stop in Gill/Montague/Sunderland/Deerfield and a major arrival had clearly taken place overnight - they were simply everywhere!

The migrant of the day would have to be Yellow-rumped Warbler (150+) with migrant groups all along the Connecticut River from Montague City down to Sunderland, and back along River Road in Deerfield to Montague City once more, a 20 mile loop on the bike. Northern Parulas (6+) featured in the early part of the ride but I didn't hear any singing after about 9:15 am. Baltimore Orioles too, were common throughout the ride and another summer breeder that clearly arrived in numbers overnight. In the evening, a surprise Eastern Meadowlark was singing on South Ferry Road on Montague along with multiple Savannah Sparrows, plus a Merlin playfully stooping at an American Kestrel!

An impressive day for this species with easily over 150 birds along the Connecticut River between Sunderland and Turner's Falls.

Good numbers of migrants moving through Franklin County in early May.
