My understanding is that non-migratory resident birds like titmice, chickadees, Carolina wrens, cardinals, etc. nest well before the migrant nesters show up. Here in NW Rapides Parish, I counted 8 cowbirds at my feeder this morning. This suggests strongly that the referenced birds are initiating nesting here.
An interesting question about overwintering vireos and catbirds would be, are they residents or merely migrants that are going north later in the spring?

The great egrets at the office park on General DeGaulle across from the McDonalds are incubating. One of the students from Tulane visiting the Woodlands Conservency banding station found a Carolina Wren nest with 1 egg. No sure of the earliest initiation of incubation for this species, but if anyone has an earlier date, you can let me know offline, or brag online. There were lots of white-eyed vireos singing, but the one we captured did not show any breeding condition (an enlarged cloacal protuberance, a brood patch would not be expected). We have still not conclusively documented whether some birds are "resident" yet.
