Interesting Fact: The female chooses the nest site, which is usually in a natural cavity or woodpecker hole in a live or dead tree, up to 100 feet off the ground and within a mile of water. Common Mergansers nest less frequently in rock crevices, old sheds, chimneys, lighthouses, holes in banks, holes in the ground, hollow logs, and burrows. They readily nest in boxes, including those designed for the much smaller Common Goldeneye. Sometimes they nest on the ground. ( https://www.allaboutbirds.org/guide/Common_Merganser/lifehistory )
Interesting Fact: Common Mergansers spend the breeding season in northern forested habitats near large lakes and rivers. Since they nest in cavities of large trees, breeding Common Mergansers are usually found in mature forests. They spend winters on large lakes, rivers, and reservoirs in the southern and coastal regions of their breeding range, and in additional wintering grounds across the northern and western United States. They tend to prefer freshwater wintering habitat over saltwater, but they may winter in coastal bays, estuaries, and harbors. ( https://www.allaboutbirds.org/guide/Common_Merganser/lifehistory )
Interesting Fact: Common Mergansers spend much of their time afloat, loafing, fishing, and often sleeping on open water. They may form flocks of up to 75 individuals. They often swim in small groups along the shoreline, dipping their heads underwater to search for prey and then diving with a slight leap.

Tom: “I managed to lose my rifle when I was in the army.”
Tom: “I had to pay $1000 to cover the loss. I’m starting to understand why a Navy captain always goes down with his ship. ”
Interesting Fact: Often when one bird dives in a large group, the others follow the leader and disappear. They can stay under for up to 2 minutes, but they normally dive for less than 30 seconds. ( https://www.allaboutbirds.org/guide/Common_Merganser/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 )
Interesting Fact: Young Common Mergansers leave their nest hole within a day or so of hatching. The flightless chicks leap from the nest entrance and tumble to the forest floor. The mother protects the chicks, but they catch all of their own food. They start by diving for aquatic insects and switch over to fish at about 12 days old.

She suspects him of cheating, so she decided to follow him today. She is literally on his tail. 🙂
Interesting Fact: Common Mergansers usually nest in natural tree cavities or holes carved out by large woodpeckers. Sometimes mergansers take up residence in next boxes, provided the entrance hole is large enough. On occasion they use rock crevices, holes in the ground, hollow logs, old buildings, and chimneys.
