119th CBC in Delaware and Maryland

Highlights this year included Calliope Hummingbird at Annapolis-Gibson Island, an Allen’s Hummingbird on the Point Lookout Count and a Ruby-throated Hummingbird on the Wilmington Count. I read (on local mailing lists; as noted by Seneca Compiler Jim Nelson) some conversations about lower numbers of chickadees and Tufted Titmouse and there may be data here to support that claim but only if you ignore (or account for) effort and weather effects specific to those counts (I’m just summarizing here, not running statistics)? Bombay Hook had a surprisingly low count of Yellow-rumped (Myrtle) Warblers. Compiler Andrew Ednie pointed out that the numbers are possibly due to a decrease in Wax Myrtle (Myrica cerifera) which, in turn, is due to coastal flooding. Similarly, Jim Nelson reports having only eight on the Seneca Count as being the lowest since 1963. They were low counts for others too, including Patuxent River (though not an all-time lc; it was missed once) and Chesterville who also noted a Cedar Waxwing low count.  These reduced tallies were possibly due to lack of berries such as those produced by the Myrica shrubs among others.

Editor Codes used in this report are bd (banded), cw (count week), hc (high count), lc (low count), nd (no details provided), and us (unusual species).
