No long lens, the one time I wished I had taken one on this trip north.
I had been watching this pond off and on for a day. Herons flew by, other birds flew by, none stopped. Yet there was always ripples in the water, and too big for frogs.
At some point light green Ferns swam around. Plants don’t swim very well. That was time to get my feet wet.
It turned out there were a pair of nest building Muskrats collecting food and bedding. I noticed reeds chewed a little later.
Adult muskrats weigh 0.6–2 kg (1+1⁄4–4+1⁄2 lb), with a body length (excluding the tail) of 20–35 cm (8–14 in). Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes. (Wikipedia)

I have another million shots of furry heads in the water. I’ll spare you and leave it with these.
Nice photos! One hard worker.
They were busy all the time 😂👍
Ah, the muskrat with their beaver like bods and rat tails – fun to photograph as long as they are NOT in your woods – those things can do major damage to banks and we are constantly having to “address” them on our stream. Had now idea they could stay that long under water.
Taken in Maine last week. We have no Muskrats in the Lowcountry, very few Beaver also. The critter you don’t want to ‘walk around’ solves this problem.
