MA - another Mourning Warbler!

 

Mourning Warbler - Deerfield Meadows, Franklin Co., MA. September 28th, 2021.

The Caldwell Road fields were admittedly quiet this morning although Common Yellowthroats were still present in good numbers along with Lincoln's Sparrows and Red-eyed Vireos. In the evening I found myself with enough time to try some birding around Deerfield. I don't normally search for passerine migrants in late afternoon/early evening but the calm, muggy and 'buggy' conditions looked promising and I soon found warblers insect gleaning around the overgrown dirt mounds in Deerfield's meadows. More Common Yellowthroats, five or so Tennessee Warblers and then a sharp, hard 'pik', clearly an interesting warbler, but which one? With my mind still wrapped around Connecticut Warblers I wondered about an alternate call for that species but it didn't seem right. After some patient waiting, the bird started calling again and eventually gave reasonable views in the evening light. It was a Mourning Warbler and an interesting looking bird to boot with a bold eye-ring, gray-brown hood and long, yellow undertail coverts, all similar features to those outlined for Connecticut Warbler. Either way, with the ID established I can admit to being thrilled with my second local Mourning Warbler of the fall. 

MA - a little more from Northfield

 

Red-eyed Vireo - Caldwell Road, Northfield, Franklin Co., MA. September 19th, 2021.

It's late September and the last few days have seen glorious autumnal days and cool, refreshingly comfortable nights. But the mostly stable air has allowed many migrants to pass through our area uninterrupted and this morning in particular there was a small but notable visible migration of southbound warblers along the Connecticut River in Northfield. Most were Blackpoll and Yellow-rumped Warblers but I was also able to pick out a couple of Tennessee Warblers and a single Nashville Warbler. Even better, I tallied my 7th Connecticut Warbler of the month when a single flew over giving buzzy 'zeet' flight calls before landing at the edge of a belt of deciduous trees and giving a loud, emphatic 'pwik' call, difficult to describe but distinctive once learned. Unfortunately, this particular Connecticut Warbler got away without being documented but I was very comfortable with what I heard, comfortable enough in fact to add it to the six I've already seen and heard in the Caldwell Road fields in September; photos and audio of two, plus audio of at least two more unseen, and three others heard well enough to be certain but simply too fast to be recorded. However, I do get the impression that we're well past the peak for Connecticut Warblers and this morning's bird was my first since the well photographed bird on Sep 16th.  The middle part of the month did host a very good showing of fairly late Yellow Warblers with five still present on the 19th.

Red-eyed Vireos have certainly been present and passing through in numbers, often in tight flocks of 3 - 4 birds but I've yet to have any luck with a Philadelphia Vireo this fall. 

While the warbler numbers may have been dwindling we are in the midst of several major waves of White-throated Sparrows, the first of which occurred on Sep 19th with 80-100 in the fields around Caldwell Road. With them have come modest numbers of Savannah, Swamp and Lincoln's Sparrows though today (Sep 27th) saw a major incursion of migrant Song Sparrows as well. Meanwhile, I did hear and sound record a lonely Dickcissel on North Cross Road, Gill on Sep 17th but decided against entering the cornfield where is was feeding to try for photos. Dickcissel is a pretty scarce migrant in Franklin County but September is probable the single most productive month to find them. 

MA - more Connecticut Warblers

A high pressure system currently settled over much of the region brought cooler temperatures with chilly, foggy dawns and delightful fall-like days. September is surely one of the most beautiful months of the year to be out birding! Such conditions generally don't see the larger scale fall-outs associated with more active weather systems but often see a steady turnover of newly arrived migrants along with the departure of the few remaining summer migrants. This particular month I've been engrossed in the day to day changes playing out in the fields near the Northfield transfer station no more than five minutes from my home. The highlight has unquestionably been the discovery of several more Connecticut Warblers. After the personal excitement surrounding the bird that showed so well on Sep 10th, I would never have imagined being gifted even better views of a different bird on Sep 16th. The latter bird showed off and posed around me for a solid five minutes having flown in totally unsolicited following a 'Trail's' Flycatcher and a Tennessee Warbler. And, much like the Connecticut Warbler that I saw in the same fields on the 10th, it seemed to be naturally inquisitive about my presence in the hedgerow as the images appear to show. While I was watching this bird I'm pretty sure another Connecticut Warbler called from farther down the hedgerow and thirty minutes earlier I succeeded in getting marginal but conclusive audio of a calling bird in a completely different spot in the fields, so certainly a minimum of two Connecticut Warblers present on the 16th. I also heard, but did not see, a further individual bird on the 15th and may have a sound recording of that one too. So, I'm reasonably happy with at least five individual Connecticut Warblers passing through the Caldwell Road fields between Sep 10th - 16th, pretty remarkable considering how difficult the species has been in previous years.

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. 

MA - Connecticut Warbler.....in Northfield!

Connecticut Warbler - Caldwell Road, Northfield, Franklin Co., MA. September 10th, 2021. Probably first-winter. 

September brings many avian riches to Massachusetts and has to be one of the most keenly anticipated months of the year for local birders. Whether it be the mass migration of Broad-winged Hawks at established hawk watch sites, or the ever present chance of finding Buff-breasted Sandpipers and other cool shorebirds among local flocks of Killdeer, every day of the month has something to offer and even just an hour outside can be time well spent. But for me, September in Western Massachusetts can only mean one thing - migration of Connecticut Warblers! The species is not an especially rare transient but can certainly be regarded as a scarce passage migrant. It's overall status coupled with skulking and unpredictable behavior make it one of the most sought-after warblers at this time of year. Within the Pioneer Valley, the flood plains of Hadley and Hatfield in Hampshire County receive the lion's share, almost all of them in reported in September. 

The situation in Franklin County is a little different with far fewer reports and only one (that I know of) actually photographed (by Josh Layfield on Sep 29, 2019). This morning I finally laid a personal ghost to rest when I shared three fantastic minutes with a Connecticut Warbler in Northfield. It flushed up simultaneously with a Common Yellowthroat providing a perfect comparison in flight. Thankfully my eyes tracked the larger, more hulking, shorter tailed bird until it perched in the shade and simply looked at me as if it were offended that I'd accidentally flushed it! Moreover, after three or so minutes of perching silently it suddenly began calling allowing me to grab a few audio clips of the distinctive, yelping 'pwik' calls. Shortly afterwards it dropped down never to be seen again.....but I still lingered hoping for more views.

Ironically, it wasn't a busy morning for landbird migrants with Common Yellowthroat and Connecticut Warbler being the only migrant warblers that I could find during a solid hour of effort.  I have seen Connecticut Warbler in Franklin County before but never well enough to attempt record shots making this morning a different experience altogether. 

In the evening a quick check of the flats at Hell's Kitchen found 7 Least Sandpipers and single Pectoral and Solitary Sandpipers amid half a dozen Killdeer, plus 15 or so Wood Ducks. 

MA - early September

 

Nashville Warbler. Caldwell Road, Northfield, Franklin Co., MA. September 9th, 2021.

The first ten days of September saw a welcome drop in the heat and humidity of August but, certainly from a Franklin County perspective, it's been pretty quiet for migration. Even the passage of Hurricane Ida on the 2nd did little to stir things up though did bring a small number of shorebirds to Northfield and an increase in shorebird diversity. The Baird's Sandpiper that had showed so well at Caldwell Road in late August lingered until September 3rd though became increasingly difficult to see spending most of its time with Killdeers on the plowed section of the fields rather than feeding out in the open grass. Two Semipalmated Plovers, two Least Sandpipers and my first Wilson's Snipe of the fall were also at Caldwell Road on the 2nd. On the 9th, heavy overnight rain brought a further 21 Least Sandpipers and 4 Lesser Yellowlegs to the Caldwell Road sod fields though the yellowlegs stayed only briefly and flew off purposefully to the south after just a few minutes never to return.

Aside from an excellent showing of Common Yellowthroats along the Connecticut River, warbler migration and diversity has been slow so far, or at least in the places that I've been able to check. A few Cape May Warblers, a couple of Northern Parulas and a Nashville Warbler (on the 9th) is all I have to show for my efforts so far! On the plus side, checking for warblers has revealed an excellent passage of Ruby-throated Hummingbirds feeding in wild habitat while taking advantage of the flowering Jewelweed along the banks of the Connecticut River, and there was an early Lincoln's Sparrow in the same habitat on the 3rd, I'm pretty sure my earliest fall record for Franklin County.

VT - Brown Booby in Bennington County!

 

Brown Booby - Emerald Lake State Park, East Dorset, Bennington Co., VT. September 2nd, 2021.

A couple of days ago I learned of a Brown Booby being seen at Lake Paran near Bennington in Vermont. Being deep in the interior and a mere 80 minutes from our house in Northfield I was quite intrigued but, judging by reports, the bird seemed quite mobile and soon disappeared only to be relocated about 25 miles north at Emerald Lake State Park a day or so later. After quickly checking the Caldwell Road fields in Northfield for shorebirds (2 Semipalmated Plovers, 2 Least Sandpipers and a Wilson's Snipe were new arrivals) I buckled up for the 90 minute drive to East Dorset hot on the heels of Hurricane Ida which had just passed south of us overnight. 

Just me, the booby and a mountain lake....

On arrival I found Emerald Lake to be relatively small surrounded by mature woodland, neatly positioned between the Green Mountains to the east and the Taconic Mountains to the west. Moreover, the lake appeared to be relatively shallow and not quite what I was expecting. The booby soon appeared and put on the most fabulous display working circuits around the lake and plunge diving frequently. To some degree the experience recalled the Brown Booby at Onota Lake in the Berkshires back in August 2018, but this bird was brighter, more mature in terms of plumage and an awful lot closer!

All in all, it was a thoroughly enjoyable experience on a beautiful autumnal day and within comfortable driving distance of home. Surprisingly, I only encountered a couple of other birders during my time there and had the lake to myself most of the time. I also noted my first migrating Broad-winged Hawk of the season heading south. 

Brown Booby has been documented in Vermont before with multiple records of at least two individuals from the Lake Champlain area.
