Excellent! It can be a nail-biter waiting for raptor parents to return to a re-nest.
So far with GHO great horned owls we've got 100% return rate for parents, even when a new nest is built more than 100' from the original blown out nest That was my most extreme case, property lines and lawyers. Bailed on dealing with them after negotiations went south and put the owls up in a friendly neighbor's white pine. Parents jumped right in within a couple hours.
Did my first Great Horned Owl re-nest project for this year's season on Monday April 21. Despite the effects of climate change on nest timing (earlier and earlier these days) New England area had a cold winter (what used to be normal) and an extended cold spring so nesting times are... historically normal for birds of all species around here/eastern Massachusetts.
Rodenticide use (SGARs Second Generation Anticoagulant Rodenticides) cases have been way up, seems like since Covid, people were home and saw more rodents? Who knows. All I know is the rehabbers I work with are seeing 2 raptor cases per week or more right now. Death rate is high but some are saved, very hard work to save them. All predator mammals and birds in Massachusetts have SGARs in their bodies/blood according to our state wildlife agency. Typically it's a random heavier dosed rodent that tips a hawk, owl or eagle into the danger zone of bleeding out internally. They collide with a branch, prey/ground, or a vehicle light hit, normally survivable but they have no clotting, the end. Unless they're found in time and treated.
On the bright side, great horned owls favor cottontail rabbits as prey around here. The rabbits love urban and suburban lawn habitat and their populations have been exploding here. Rabbits (lagomorphs not rodents) do not get into SGARs bait boxes. Bring on the great horned owls! GHO's stil get into rats, mice, etc that are stumbling around dying from SGARs.
The two kids right after placement in new nest at 70', about 30' from a second white pine where their nest blew out from a few feet lower in a heavy wind storm. Long story why the new tree for another day.
