Hooded Mergansers & Feeding Adaptations

4-16-14 female hooded merg eating fish IMG_9199Although most of New England has Hooded Mergansers year round, we see them most frequently in the spring and fall, when Canadian-nesting individuals are migrating north. They stop to re-fuel in wetlands where they are well adapted for capturing and eating fish, insects and crayfish. The nature of the changes their eye lenses can make, coupled with the high degree of transparency of the membrane that covers their eyes under water give them superior vision under water. Their success in holding onto the struggling prey they capture is greatly increased by the serrated edges of their slender bill. (Photo: female Hooded Merganser)

    What a fabulous photo! Are mergansers in the duck family?

    • Yes, they are in the subfamily Merginae (scoters, eiders, mergansers, etc.), of the family Anatidae (ducks, geese, swans),

    A pair were resting at our nearby beaver pond the other day. I am hoping that they will stay around.

    Amazing capture here! In the photo is that a younger female I’m curious, also can she really consume that big (and frantic!) looking fish?? Does the fish put up any fight and does it get swallowed wriggling the whole way/time?! Keep up the interesting photos! 😉

    • Yes, I believe it’s a juvenile bird (not sure of gender). Not sure how much of a struggle it gives as it’s being swallowed, but it was swallowed!
