Species: Wilson’s Warbler
Most recent capture date: 5/08/2022
Age: one year old
Sex: female
Notes: This time of year at our Jasper Ridge site, we get two groups of Wilson’s Warblers: all are migratory, but for some this site is just a stop on their way north, while for others it is their destination for the breeding season. This bird is just passing through. Interestingly, our breeders tend to have more black in the crown, even on females; it would be unusual for an individual that looked like this to be breeding at our site.
