Great recording of a Leach’s Storm Petrel! And the Field Sparrow singing is a positive sign too- this regular Spring visitor bears watching. The 2nd MBBA had one confirmed breeding in NW NB. There may have been more since (?).

By civil sunrise on 18 May and 21 May only 3 to 4 warblers were heard during each of these nights. In contrast, in the 1 to 3 hours after civil sunrise, up to 19 warblers of 7 species and 27 warblers of 8 species were heard on these dates respectively during the 3 5-minute count periods. Except for Black-throated Green Warbler and Yellow-rumped Warbler, most of the warbler sounds heard were night flight calls rather than chip calls or songs. This would indicate that these warblers were still on the move. The migrating warblers included Blackpoll Warbler, Magnolia Warbler, Yellow Warbler, American Redstart, Black-throated Blue Warbler, Blackburnian Warbler, Common Yellowthroat, and Cape May Warbler.
