Yesterday I posted some images of male Northern Cardinals and a male Pyrrhuloxia. These birds are close relatives. The males of the two species are easy to tell apart. It’s not so easy with the females. Can you identify which species this bird belongs to?
If your guess is female cardinal you probably wouldn’t be alone, but you’d be incorrect. This is a female Pyrrhuloxia.
Here’s a female Northern Cardinal. Can you see the obvious difference?
The major difference between the females of these two species lies in their beaks. Pyrrhuloxias have ivory-colored curved beaks. Cardinals have red, wedge-shaped beaks. Yes, there are plumage differences as well, but at a distance the beaks are the easiest identifiers.
Here are the two species, side by side.
Yes, they look a lot alike. But, those beaks never lie. The Pyrrhuloxia is on the left, the cardinal is on the right.
