For the month thus far, temperatures were slightly cooler than normal and we had just a bit above average rainfall (3.14 inches). The cool weather slowed leaf development, which was helpful for getting looks at the newly arrived passerines. The chilly temps also caused some birds to concentrate around available food sources.
New and arriving birds this week:
Chimney Swift (5/25)
Great Horned Owl (5/26)
Yellow-bellied Flycatcher (5/24)
Alder Flycatcher (5/23)
Olive-sided Flycatcher (5/21)
Great-crested Flycatcher (5/23)
Eastern Bluebird (5/24)
Swainson's Thrush (5/24)
Wood Thrush (5/27)
Cedar Waxwing (5/21)
Philadelphia Vireo (5/24)
Blackpoll Warbler (5/28)
Mourning Warbler (5/21)
Wilson's Warbler (5/28)

Wood Ducks, American Wigeon, Gadwall, Northern Shoveler, both species of teal, Ring-necked Ducks and Common Goldeneyes were all seen in good numbers at Lake Josephine this week.

A decent (and likely, final) wave of northbound shorebird migration moved through the area in the past few days. High counts of 22 Least Sandpipers and 80+ Short-billed Dowitchers were the peak numbers at Lake Jo on the 22nd. The last migrant Solitary Sandpiper was seen on the 25th in the Connor unit of the Aroostook National Wildlife Refuge.

One last Snowy Owl was reported in Fort Fairfield on the 25th!
A few arriving Chimney Swifts were seen despite the nasty weather. The first arrivals include one in Sinclair on the 25th, another in Fort Fairfield on the 26th and numbers reported in Patten on the 27th.

Most of the remaining breeding flycatchers arrived on schedule in central Aroostook. Alder Flycatchers were first heard near the Little Madawaska River Dam in Caribou on the 23nd, Great-crested's were loudly announcing their presence in Woodland on the 24th and Yellow-bellied's were picked up in a bog in New Sweden on the 25th. Still no sign of Eastern Wood Pewee or Willow Flycatchers...yet.
A Horned Lark was singing in a potato field near the Caribou Airport on the 25th. After a long absence, the first Cedar Waxwings have begun to reappear in the area. The first arrivals I found were a group feeding over a wetland in Cross Lake Township on the 21st.

A pair of Eastern Bluebirds arrived in my yard in Woodland and checked out the accomodations for a while. Apparently they found none of my nest boxes to their liking and moved on. Other bluebirds were reported in Portage Lake, Stockholm and Oxbow. Swainson's Thrushes were quick to establish themselves in wooded wetlands across the area and a Wood Thrush was heard singing in Mt Chase.
Warbler migration has probably peaked this week with the arrival of Mourning, Blackpoll and Wilson's Warblers... In all, twenty one species of warblers were seen in northern Maine this week. Mourning Warblers were heard in Cross Lake Township (formerly T17R5) and at the Connor unit of the Aroostook NWR. Blackpoll Warblers were heard in Cyr Plantation and a male Wilson's Warbler was back on territory along the Muscovic Road in Stockholm.

American Goldfinches and Purple Finches have started to disperse away from feeders but several of each are still making daily visits to my feeders.
A pair of Evening Grosbeaks are also stopping by, albeit more intermittently. Other Evening Grosbeaks were seen in Caribou, Cyr Plantation and New Sweden. After quite a few hours in the big woods this week I failed to encounter any White-winged Crossbills this week.
