: mid-late May and late Sep-late Oct, with from mid Sep and to early Dec. Prefers open areas with weeds and low shrubs and places where migrants gather
: with eight widely spaced records mid Dec-late Mar, except for two 2024/2025; Mt. Desert Dec 2, 2024 to at least Mar 4, 2025 and Bar Harbor Mar 1, 2025, the later being present for some weeks prior to the above report. At least five spent multiple weeks at feeding stations.
Miscellany: Probably under reported, especially in fall, when passage comes at a time when few observers are in the field. Late Aug-early Sep records need to rule out the somewhat similar Tennessee Warbler. With generally warmer winters, we can expect an increase in the number wintering Orange-crowns.
