Subject: [OrangeCountyBirding] a maxima of minima
The six Cackling Geese (all minima) continue around the lake at Mason
Regional Park in Irvine. Interestingly, I noted that only one had a bold
black gular (chin) stripe, which is found in "most" leucopareia (Reeber
2015). The darkest four birds are immatures in various stages of formative
molt, with only one having a drizzle of white across the base of the
foreneck. The largest bird is an adult that leads the group when it takes
flight and is the most vigilant when it is foraging. This presumed male is
one of two individuals that have insubstantial white bands across their
forenecks. The other is a smaller bird (female?), and is possibly an adult
that has yet to complete its molt into basic plumage. So, while I'm no
goosologist, the possibility exists that this is a family group of minima
that has found our Orange County grass to its liking, and is by far the
highest number of this subspecies I've seen locally.
