I had a nice surprise the other day as I posted an owl I'd photographed on iNaturalist and the first computerized suggestion was brown fish owl, an owl I'd never heard of. I looked it up on Wikipedia and Birds of the World and determined it was a brown fish owl and posted it. It was a new "lifer" for me, the first time in my life I'd ever seen one. I was thrilled when Brenna Farrell, the number one identifier of brown fish owls on iNaturalist (by a 6.5 to 1 margin) and probably the number one identifier of all owls on iNaturalist, confirmed it. We saw it on our fifth and last safari in Ranthambore, in zone 5, our second time in that zone. My notes from that day do not indicate what kind of owl our guide said it was, and he may not have said.

| I took lots of photos, but the owl never moved, so they are all the same. |
There are four subspecies and we saw ssp. leschenaulti, found in India through Myanmar to west Thailand. and known as the common brown fish owl, distinguishing it from the other three ssp. Birds of the World has two illustrations, but not leschenaulti. I picked the illustration of ssp. zeylonensis, the Sri Lankan brown fish owl, found in Sri Lanka, which looked closer to leschenaulti than the other illustration. Leschenaulti is a little larger and lighter than zeylonensis.
I've also included the range map from Birds of the World.
Wikipedia states, "The brown fish owl has prominent ear tufts and rufous brown upperparts that are heavily streaked with black or dark brown. Its underparts are buffy-fulvous to whitish, with wavy dark brown streaks and finer brown barring. Its throat is white and conspicuously puffed. Its facial disk is indistinct, the bill dark and the iris golden yellow. Its featherless feet are yellow. Two-year old brown fish owls are somewhat paler than adults. Female and male differ slightly in size." The feather pattern on the wing and the chest are what sold me on it.
As the name suggests, it does include fish in its diet, something I've never heard of owls eating.
