is always interesting because a new bird might arrive any time. The first groups that arrive are usually males, but not long after that, you will see females appear. In these photos, the shiny ones are male birds and I think the other bird is a female. Some females do have a brownish washed-out look too. They might not shine as gloriously but they have the same majestic yet goofy look as the males. (Plus - rain on Gracks is beautiful too!)
