Gulf of Maine During a whale watch cruise out of Bar Harbor on August 24, a Procellaria petrel was found on the water among Great Shearwaters. Initial comments on the photographs all point to WHITE-CHINNED PETREL which would be the first for Maine and only the fourth for North America. It has not been seen on subsequent outings. On August 27, the Bar Harbor whale watch in the morning came across two SOUTH POLAR SKUAS, a PARASITIC JAEGER, RED and RED-NECKED PHALAROPES, and LEACH'S STORM-PETRELS. Once again, DICKCISSELS are being found on Monhegan this week. Seawatching recently from Monhegan has produced the four shearwater species, including CORY'S, and a multiple PARASITIC JAEGERS.

An immature LESSER BLACK-BACKED GULL continued on Clark Ledge in Eastport through August 22. The Burn Road, off Route 1 north of Topsfield, produced BOREAL CHICKADEES, a pair of BLACK-BACKED WOODPECKERS, and a male SPRUCE GROUSE at mile 8 and another at mile 6.5.
