unusual Mallard behavior?

[JeremyWinick]

Yesterday evening I spotted a pair of Mallards sitting on the apex of a
roof in our neighborhood (Bradburn, in Westminster, Adams County). There
are many Mallards around the Big Dry Creek and nearby ponds,  and I have
seen them in the neighborhood, but never "perched" on a rooftop. I only
had my cellphone as a camera, so the resulting picture is poor, but
clearly shows the birds on the top of the roof.  Surely not a nesting
spot since the roof falls away steeply .

Surveying the surroundings for places promising food or nesting sites? 

A couple of years ago, I saw a pair of Canada geese landing on top of the small area above the clock of the County Courthouse in downtown Boulder.  They loudly announced their presence, strutted around a bit and took off again, evoking memories of Jonathan Livingston Seagull.

Reminds me of a Canada Goose I saw last month perched up on top of one of the zoo buildings overlooking Denver City Park. I don't recall ever having seen geese on rooftops and remember thinking it odd enough to snap a photo at the time. Probably wise, wouldn't want to land in the wrong cage...

I know this was not in CO but we recently hiked Smith Rock SP outside of Redmond, OR. Along our 3.5 mile hike along the river we saw an estimated 150 Canada Geese & what were most of them doing? Roosting & possibly nesting 800 to 1000 ft above the river on the cliffs. It was very bizarre to see. They were very noisy also. Any mallards were all in the river tho.
