Pigeon House?

Found this on one of my bike rides this spring.... I've put in 57.3 miles in April so far... more than I've ever done in April before. A combination of some pretty nice early spring weather, and my feeling so glad to be out and about and energized, after a winter of way too many doctor's visits, diagnoses, treatments, and days upon days of lethargy - or "cancer brain" as my sister-in-law Anne calls it!

A worker nearby told me that this is a very old pigeon house. Some digging on the internet got me nothing besides a close-up photo of one side of this pigeon house with it's 10 roosts. A call to Linda Palmeri - retired head of Parks and Recreation for the City of Rochester - and one of my granddaughter's other grandparents - yielded the info that there used to be more of these, and they were built/funded by the Audubon Society many years ago,
She also revealed that there are or were, a couple of bat houses, and a hummingbird house! I've got to see if I can find those?
