Interesting Fact: Bufflehead nest only in cavities, using holes dug by Northern Flickers and sometimes Pileated Woodpeckers (as well as artificial nest boxes). In the summer, females that are too young to breed, or whose nests have failed, fly around in noisy groups and scope out the available nest holes for the following breeding season. Just before laying, females make more secretive flights to prospective holes, either alone or with their mates. They usually choose cavities in poplar or aspen trees, except in California where they often use pine trees. ( https://www.allaboutbirds.org/guide/Bufflehead/lifehistory )
A duck walks into a bar and says to the bar tender “I’ll have a beer”.
The bartender says “Hey! where did you come from?”
The duck says “I’m working the construction site across the street”.
And the bartender says, “Well why are you working construction when you could be making millions in the circus?”
And the duck said “What would the circus want with a brick laying duck?”
Interesting Fact: You may see gulls trailing flocks of foraging Common Mergansers. They wait for the ducks to come to the surface and then try to steal their prey rather than fishing on their own. Occasionally even a Bald Eagle will try to steal a fish from a merganser. ( https://www.allaboutbirds.org/guide/Common_Merganser/lifehistory )
