The Night Heron (Nycticorax nycticorax), photographed hiding amongst the branches wears a size 45 short (he is a lot more stocky than his other heron brethren).
This one appears to be a juvenile – his feathers are a lot more grey in color than the adult white. Not surprising since there are many birds nesting in Wakodahatchee this season.
I caught this one in full cry with a Canon 300L f/4 IS hand-held.
