And as to the in/flyover/heard split....lets see...
30 Seen in the garden (including Wood duck pair that landed in a tree during the rain on Monday, upgrading their status.)
11 Flyovers. With the exception of Common Raven, I'd be surprised (thrilled!) if any of these get upgraded. Mostly hawks and visitors to the lake.
2 Heard only - Barred Owl and Common Loon. Touch wood we've seen the BAOW in the garden every year so far, and generally see the Loons flying over at some point.
Over the almost five years we've been at this address, I believe only one of my 100 remain a heard only - Eastern Whipoorwill. Which was on the roof and heard very very clearly!
Dad, does that mean you've upgraded Tawny Owl to seen, or just heard in?
