Here's some birds I found in California. I was told these were ruddy ducks and great tail grackles. For both, is there a way to tell if it's female or immature male? Thanks! ruddy_duck_female_black_cheek_stripe1.JPGruddy_duck_female_black_cheek_stripe.JPGgreat-tail_grackle_or_brewers_blackbird_female.JPG

Sorry, I am not sure what happened. I thought I had deleted my draft when I looked again at the title, but I must have posted it instead.
At this point in the winter, I think a young male Ruddy Duck would be starting to show some signs of its gender, so I think your bird is likely a female. Juvenile Great-tailed Grackles tend to look messier on the breast, so I think that is a female too.
