Leaving. Lots of birds here, but I sort of have to conclude that ♀1117 is gone and that there is currently no breeding ♀ here. There are lots of ♂, inc. 3 that have apparently been (mistakenly) deleted from the field list. *Group update* ♂8? 1026 & 1027 both fledged in 1985 and disappeared prior to being sexed. I'm changing both of them to "moved" in August, and will add them both back ("returned") as of 1 February, ± 2 months. 16 April Ambushes last night netted only 1 bird: #632, which finally would appear to solve the mystery about who the breeding ♀ here is! (This bird disappeared from here during winter 85-86.
