Observation details
Updated notes: HERGxCAGU is best fit after conferring with review team. Original notes: Possible CAGUxHERG. If HERG, this is a less-patterned juv HERG than any other I can find on Macauley. Inner primaries are lighter - if you squint - otherwise not overly convincing. If CAGU, the dark bill is later than any other dark-billed juv CAGU I can find on Macauley. It appeared equal in size to the handful of adult CAGU it was associating with.
