Hi Jill,

There are plenty of cement structures along the North Sea coast in Europe as 
well as along the Atlantic and Pacific in North America, plus Wollongong 
harbour, NSW, with roosting shorebirds.

I have had regular sightings of the following species roosting on cement 
Eurasian, American, Black and Sooty Oystercatcher
Purple Sandpiper
Rock Sandpiper
Ruddy and Black Turnstone
Wandering Tattler
Common Redshank
Lesser Yellowlegs

Obviously, this is just a snapshot and most likely I could come up with way 
areas and species.

Hope that helps.

Hi Everyone,

Please, I need information if you could take a moment to think.

Does anyone know of a situation where coastal migratory shorebird flocks roost 
regularly on cement structures, as in a sea wall or revetment wall? It doesn't 
have to be in Australia, although that would be better if possible.

If there is such a situation, the next thing I would like to know, if possible, 
is which species are prepared to stand on concrete.

Taking the question further, I would like to hear from people who know of 
shorebirds roosting on other artificial structures or surfaces. I'm not asking 
about birds like cormorants or pelicans, rather, migratory shorebirds.

The answers may help in informing for an upcoming proposed artificial roost. 
no, I am NOT building another artificial roost, not me. The politics of the 
one turned me into an old woman.
