For the Birds

My mom has a birdbath on the back patio, and she enjoys watching the variety of birds that come to drink and to bathe.  This winter, I have seen more species than usual:  the American robin, scrub jay (not a pinon jay), various sparrows, various finches, various juncos (winter only), European starling (winter only), American crow (winter only), mourning dove, northern flicker (winter only), and ladder-backed woodpecker (first time I've seen them).  We had another rare visitor a few weeks ago:  either a sharp-shinned or Cooper's hawk.  It hung out at the birdbath for an hour and a half (and scared other birds off for that period).  Strangely, I have not seen any greater roadrunners this winter, which we normally see.  Overall, it's not a bad variety for a urban/suburban birdbath in a part of the country not known for its trees.
