Roof-top Birds

Over the last couple of days I have been noticing the birds up on the roofs of the homes at Avimor. Robins are regulars on the roofs. The pair of Say's Phoebes are still flitting about the roof tops. Occasionally I'll see Kestrels, Starlings, and Red-Winged Blackbirds up on the roofs too. But the two most interesting that I have seen in the last two days were Killdeer and Quail, birds which are most commonly found on the ground. The California Quail were on top of the Sales Office roof this morning when I came to unlock and I have seen the Killdeer on a couple of different homes. Strange behavior!
