Hooded Mergansers

How do you get a frog off the back window of your car?

Use the rear defrogger.

Interesting Fact: Hooded Mergansers are usually in pairs or small groups of up to 40 birds. They court in groups of one or more females and several males. The males raise their crests, expanding the white patch, often while shaking their heads. Their most elaborate display is head-throwing, in which they jerk their heads backwards to touch their backs, with crests raised, while giving a froglike croak. Females court by bobbing their heads and giving a hoarse gack.  ( https://www.allaboutbirds.org/guide/Hooded_Merganser/lifehistory )
