They occasionally escape and can be seen in local marshes.

While working as a naturalist on cruise ships in the Antarctic region, I came across a species of duck which eats meat and made this post.

A Carniverous Duck: the Yellow-billed Pintail | Miles Hearn


In May-time, when the lilac-plumes
Droop from the branch their purple blooms;
When chestnuts clap their leafy hands,
And every bud with joy expands;
When in the moist, sequester’d nooks
Of woods is heard the call of brooks,
The wood-duck builds its downy nest
Secure from prowling schoolboy’s quest. -McClellan

    What a wonderful, fascinating guide! You could give an online course in bird identification! I’m sure there would be interest in this, given all the bird watching which has become so popular during the pandemic. Ducks that have developed a taste for seal meat. Who knew? And a thank you also to Eddie for the wonderful Owl and Hawk photos. Thanks, Miles!
