Osprey are not strictly territorial, as in other fish-eating birds. Fish are a mobile resource, hard to defend, making efficient defense of feeding sites unfeasible.
Male osprey will defend their immediate nest site, sometimes reaching out as far as 0.5 km, but in some situations, where the fish are plentiful osprey will nests “colonially,” with others. (e.g., inland Florida; Lake Istokpoga).
On wintering grounds, individuals are known to congregate where fish are abundant, but are generally more spread out, averaging 0.7 Ospreys/km in coastal mangroves in southeastern Brazil.
Ozzie is a little bit different. He has what some birds might consider a character flaw.
