Catbirds Put Off?

The catbirds this year face a bit different environment than this time in 2012.  The berries are no more!  The Leatherleaf mahonia were quite a draw but I am more interested in native vegetation.  Hence shrubs gone, and catbirds seemingly confused.  I see them take a crack at the various feeders and to some extent the suet is a good attractant.  But for the most part they skulk--and sulk.  The takings are a bit slim right now.  I'm sure they will do fine once the season really gets underway.  And if they're patient, fruit choices will be quite good in two or three years!
