31st March
The next day we were due to visit a couple of state parks and look at a roost in the evening. It was getting hot before 9am and the rangers had closed some of the trails at Estero Llano Grande State Park due to flooding. We also discovered that Santa Ana National Wildlife Refuge had been closed completely.
We decided to do the trails that we could and perhaps spend some time at the feeding station, watching from the shade of the main building.
We stayed the whole day as our second park visit was not possible. In the evening we went to Oliveira Park, Brownsville to watch the parrots coming in to roost. We saw around 200 Red-crowned, a single Yellow-headed as well as Green Parrots.
1st April
Another drive on to Benston-Rio Grande State Park. Situated next to the wall separating the U.S. from Mexico there was a lot of guard presence and activity. We spent the day, walking various trains in the heat and were grateful for the trying for Elf Owl as darkness descended.
2nd April
Salineno Bird Preserve
This reserve had been closed and the gate locked. It wasn't clear whether this was to do with weather, funding (some reserves were not putting out food rather than spend funds that they had allocated for that purpose) or the proximity to the border. We met some birders that had already been spoken to by border guards before we arrived.
