Spring has finally sprung, as many migrating birds were coming through. We had a total of 111 species, none new this time so our cumulative total remains at 266.

Species of interest included Bell’s Vireo in areas 1, 2, & 3; decent numbers of Yellow Warblers,  Wilson’s Warblers and Yellow-breasted Chats throughout;  Black-headed Grosbeaks in areas 2, 3 & 5; W. Tanager in area 2; Pacific-slope Flycatcher in areas 2, 3 & 5; Ash-throated Flycatcher in areas 3 & 5; and Lazuli Buntings in area 3.

Least Turn update:

A small migrating flock (4-8 individuals) of Least Terns arrived in the lagoon on 25 April and stayed for just three day.  On 6 May a larger group of terns with 14 individuals arrived and began landing on the western sites of the lagoon. As of 8 May there were up to 22 Least Terns with two to four pairs site selecting at both western sites.
