Thanks for the insight, just yesterday I was wondering how the robin got the 
mud to the nest, maybe in dobs like swallows, this method is a whole lot 
more efficient for that adobe cup, maybe someone else has seen how the 
grass/vegetation gets it mud coat. Keep looking, you never know what is 
awaiting to be discover.   Nancy in Danby
