Striated Heron, Butorides striata
There seems to be some controversy about this heron group.. this bird is one that falls within a series that is now broken up into different names.. and to be quite honest I’m not even sure if this is still called a Green Backed heron or just a Striated Heron..
There is now a Green Heron, which is found in North America and Panama which for all I know looks the same as this bird… so here’s a few photos and maybe someone will recognise it and tell us more…
