Ali et al. - wonderful experience, urban/suburban flat gravel roofs are an ecological niche.  Back in 1965-69 when our older daughters were in grade school, I banded flightless young Upland Sandpipers (then known as Upland Plover and along the way even as Bartramian Sandpiper) found on the mowed portion of the school lawn.

In chatting with the school custodian during my visits, I learned that he observed adults frequently on the roof where he thought they nested before juveniles appeared on the lawn and roof visits ceased.  The roof appeared to provide some nesting sanctuary from those parts of the lawn which were frequently and regularly mowed.

Great story Ali. I used to work up on roofs at night with infrared imagers and it was so easy to see the Killdeers who seemed totally perplexed that I knew where they were. Even when they flew off the next, the eggs remained very warm and, to me, visible. The advent of all rubber, no gravel roofs means less nesting habitat thought U32 in East Montpelier installed a couple square yards of gravel just to try to attract them.

This roof has been habitat for the shorebirds every year, but they have blended in so well with the multi-colored round stones, they've always eluded my detection. Regardless of my endless searching and waiting for a changing of the guard, I've never found them (like looking for that one jigsaw puzzle piece that MUST be missing). Until now! Like Horton the elephant, the Killdeer are faithful 100 percent! The snow is melting on the parent on the nest while it covers the roof around them and eliminates their ability to hide.
