March 26th was one of those bigger migration days when warm conditions coupled with an occluded front brought rain, thunderstorms and a lot of avian action! Widespread arrivals of Eastern Phoebes and, to lesser degree, Tree Swallows occurred that day as well as 30 newly arrived Green-winged Teals at Barton Cove. Just upriver, Ted Gilliland was busy sorting through a smaller flock of 13 Green-winged Teal and ultimately found a nice example of the Eurasian sub-species, certainly the first that I've seen or even heard about in Franklin County! Later that day, eight Bonaparte's Gull graced Barton Cove, along with five (early) Double-crested Cormorants and a Common Loon in full breeding plumage. And....I would have loved to have seen the flock of five migrant Sandhill Cranes reported by Eric Huston migrating high over the cove a little earlier in the afternoon. Overall, that was a pretty decent haul of migrants for the 26th!
Barton Cove continued to host a fairly large flock of Ring-necked Ducks with over 100 present, often loafing around Barton Island and subsequently difficult to see at times. Up to two Lesser and seven Greater Scaup (on the 28th) were often present with or near the Ring-necked Ducks.
Waterbirds aside, the incursion of winter finch species continued to be a major attraction for me and over the last month or so I've been very drawn to the Montague Plains which continues to host large numbers of Red Crossbills, the numbers of which appear to fluctuate on a day-to-day basis as the birds roam, presumably in search of the most productive feeding spots. Red Crossbills peaked at a whopping 360 birds on March 25th, a day which also saw 55 Pine Siskins and over 200 Dark-eyed Juncos and the first local Pine Grosbeak that I've seen for weeks. The day before saw 22 White-winged Crossbills in the plains with smaller numbers continuing through to the end of the month including 17 on the 31st. The Montague Plains have also proven to be a good spot for migrant Fox Sparrows with up to five present on the 19th, and the first territorial Field Sparrows started to appear for another breeding season from March 28th.
The last two days of the month saw increasingly warm temperatures with first Yellow-bellied Sapsuckers and Pine Warblers in the Montague Plains as well as some odd migrants such as two immature Red-shouldered Hawks and 5 Rusty Blackbirds on the 30th, and a Belted Kingfisher heading north on the 31st. The latter date also saw a late afternoon arrival of 17 Double-crested Cormorants at Barton Cove.
