It was supposed to attract Purple Martins but the Sparrows got there first.
Many generations of Sparrows have taken their first flights here over the years, but eventually the harsh weather took it's toll, the roof fell in, the plywood buckled, the paint peeled, and it had seen better days. Not many of the 27 apartments were still warm and dry, and the birds decided to look for more suitable accommodation.
Then The Space Cadet came along and magically rebuilt it. And the birds moved back in.... still no Purple Martins, but lots of Sparrows.
The rings around the holes are repairs made after an enormous black squirrel climbed the post last summer and made a meal of some of the babies, and tried to make a meal of the birdhouse too.
Ha! Damn tree rats!
This year we've enjoyed watching lots of families grow up and take flight. This hardworking mum spends all day feeding 4 hungry bossy squawking noisy chicks. And it's mum doing all the work, I've only seen dad there a couple of times.
I suppose he's busy at the office.
