Ok Brush made me think, so I did some timeline building. Here is what I found on blogs, Texbirds and eBird reports. 21 April Some intereactions with a several NOMO and some preliminary nestbuilding, that may have involved more than one NOMO 22 April More interactions with a NOMO, who is singing. Several people noted the Tropical is silent or makes only chirp like responses 24 April Active nest building with NOMO 26 April Obvious pair bonding, both birds actively defending nest area against other mockers. Bill and Mavis noted Tropical as female in their notations on eBird, same date Dan Pacamo noted in his blog he saw the two mating and Tropical was receiving. 2 May Kenneth Bader noted Tropical On Nest 12 May Several people noted both birds sharing nesting So if the birds had a sucessful mating, there should be babies within approximately a two week period of the first week in May. 18 May Kenny Nichols noted he and his wife observed the birds making frequent trips to the nest with food. Assuming birds hatched a few days prior would expect nestlings to fledge by the first week in June. 9 June Steve Mays reported the nest seems abandoned. After that there were multiple reports of babies in nest or out of nest, and then making short flights in limbs of trees. Parents feeding them and so on. So I am going with Tropical is female and mother of hybrid young. Vicki Crutchfield Live Houston and work in Galveston, TX Cell : 409-789-1178
