But one osprey in the Trossachs has made life even harder for himself this year by setting up not one, but two families to take care of. The drama started when the osprey, nicknamed Drunkie after a local loch, returned ahead of his usual mate, Katrine, and bonded with a new female, Arklet.
But he soon slipped back into his old routine with the arrival of his former paramour, and has continued to mate with both females.
His story is being caught on camera and relayed live to The Lodge Forest Visitor Centre in Aberfoyle.
Lucy Tozer, the wildlife information officer for the Aberfoyle ospreys, said: "We watched Drunkie with both females for several days before Arklet disappeared from view, and we assumed that she'd left the area. But when we visited the nest to fix a camera issue, we found a second eyrie, and Arklet incubating what we can only presume is a clutch of eggs."
