    Black-throated Blue Warbler / Setophaga caerulescens

    : Breeds. to late May-late Jul primarily on slopes with mixed woodlands, good-sized trees and a distinct understory. Trails along the east side of Beech Mountain and the valley between Pemetic and Cadillac Mountains are favored locations.

    : - early May-early Jun and mid/late Aug-early Oct with from late Apr and to late Oct/early Nov in deciduous and mixed woodlands and where migrants concentrate.

    : Hull's Cove Nov 24-at least Dec 13, 2023.

    Miscellany: Black-throated Blue is one of the few warblers where the males look essentially alike regardless of age or season, and are very different from the females. Early ornithologists including Audubon thought male and female Black-throated Blues were two distinct species.

    A Jan 29, 2012 record of a bird found dead in Northeast Harbor while possibly correct, lacks supporting details.
