Only the bigger lakes in the region are still ice covered. Our favorite central Aroostook impoundments Christina Reservoir and Lake Josephine, lost their ice on the 28th this year. Water levels in streams and rivers remains quite high with the St John River just reaching flood stage late last week due to snowmelt.
Hardwoods have begun to flower and amphibian and insect activity has increased substantially.

Waterfowl diversity took a big jump in the county this week with ice-out occurring at the premier duck ponds: Lake Josephine in Easton and Christina Reservior in Fort Fairfield. Eighteen species of waterfowl have been reported this period.
Snow Geese returned to the St. John River flats in Grand Isle last week. Over 500 were estimated to be feeding in the potato fields there on the 27th. 13 including one Blue phase were also spotted in Madawaska on the 3rd. Flocks of Canada Geese continue to be reported as they move through. As mentioned earlier, many locally breeding Canadas are already on nests.
A Long-tailed Duck and a Bufflehead arriving as the ice left Christina Reservoir on the 29th were also notable. These were joined by more of their kind by May 4th at Lake Josephine. Yet another Long-tail was spotted by the UMPI Ornithology class on Presque Isle Stream in Presque Isle on the 3rd. Greater Scaup were spotted in Grand Isle 3 May and at Lake Jo 4 May. Black and Surf Scoters put down into Christina Reservoir on the 4th. Three males were the first Ruddy Duck arrivals at Lake Jo on the 4th.
The first Pied-billed Grebe was heard calling at Christina Reservoir on the 26th. Another was heard near the Muscovic Road in Stockholm on May 1st. A special discovery was a Red-necked Grebe photographed in breeding plumage on Lake Josephine on the 1st. The attractive diver is seen in Paul Cyr's photo at the top of this post
A Great Blue Heron was photographed in Littleton on the 27th and other was seen at Easton on the 2nd. A Turkey Vulture was seen feeding on the roadside in Conner Twp on the 4th.
Birders found a good diversity of raptors in northern Maine this week with 11 species noted. Bald Eagles continue on the nests at Ashland, Fort Fairfield, Presque Isle and Van Buren. Ospreys are also now occupying most nest sites in the area including the large nest on the power poles near Route 1 in Van Buren. A previous report noted a young Bald Eagle adding sticks to the structure...
Sharp-shinned Hawks were seen in Fort Fairfield on the 23rd, as was the first arriving Broad-winged Hawk of the year. A Red-tailed Hawk was a Square Lake Township on 1 May and a Northern Goshawk flew over Barren Lake in Caribou on the 28th. A large Coopers Hawk was chased by an American Kestrel near the Presque Isle Airport on Wednesday the 4th.
Always a notable sight in Aroostook, an adult Peregrine Falcon was spotted feeding on a Ring-billed Gull beside the Roosevelt School in Hamlin on the 3rd. Merlins were seen and heard in Caribou on May 1, Quimby (Winterville) on 25 April and Stockholm on the 25 April and 1 May. American Kestrels were widely reported.
Boreal Chickadees were heard on the Muscovic Road on the 1st of May and Gray Jays were spotted in New Sweden on May 1. Both Ruby-crowned and Golden-crowned Kinglets are singing loudly the conifer woods these days. The first Ruby-throated Hummingbird for the county was reported from Stockholm on the 3rd...early for sure.
The first Blue-headed Vireo of the year arrived on schedule at New Sweden on 1st. Loud couplets announced the arrival of a Brown Thrasher at Presque Isle Airport on the 4th.
The first warblers of the season were trickling in to northern Maine as April gave way to May. Yellow-rumps were reported across the area in moderate numbers. Other warbler arrivals in central Aroostook included Palm Warblers at the Muscovic Road in Stockholm and the Burnt Landing Road in Cross Lake Twp on the 1st; a Black-and-White Warbler at Mantle Lake Park in PI on the 1st; a Northern Parula at Madawaska Lake on the 3rd; a Black-throated Green Warbler at Barren Lake in Caribou on the 3rd; Northern Waterthrushes at Arnold Brook Lake in Presque Isle on the 3rd and Collins Pond in Caribou and Christina Reservoir in Fort Fairfield on the 4th.
Notable change in the finch department were lots of Purple Finches arriving at the end of the month.
Evening Grosbeaks continue in pairs and small flocks at Castle Hill, Caribou, Fort Fairfield, Fort Kent, New Sweden, Portage Lake, Presque Isle, St. Francis, St. John Stockholm, Winterville and Woodland. Though most have now departed, small numbers of Common Redpolls are still being reported around the area. A Hoary Redpoll was part of one of the last flocks to visit my feeders in Woodland on the 23rd. A handful of Pine Siskins were seen (Caribou, Madawaska Lake, Presque Isle, Woodland) and numbers of these seem to be increasing.
