Lots of Martins at HBMO

There was a large influx of martins over the past 4 days. At last count 21 pair were in residence at the colony site. The numbers grew from 4 martins  to 42 in a matter of days and all the recently installed tree swallow boxes were now occupied. It will be time to bring 12 more gourds for the rack on the next visit. The sub adults will need accomodation.HBMO Set Up 2015 Trio Castle Tree Swallows HBMO
