37 LLWoff 1964 Journal July 10 Laguna Atascosa Refuge, to Brownsville, Cameron Co., Texas. Up at 8:00. After breakfast Dick drove me out to Laguna Atascosa To watch Botteri Sparrows. I soon located a chipping adult carrying food - territory #8, on both sides of road beyond ferns. #4 & Watched this pair for most of morning until 10:30 when Dick returned from airport. He had gone to locality of open grassland now being overrun with a succulent like Salicornia + several other small perennial herbs of xerophytic + probably halophytic nature. Found Cassin's Botteri Sparrows together apparently inhabiting same sorts of vegetation. There was some Spartina-dominated areas nearby but Botteris were not limited to these areas. He found nest of Botteri containing 7 white eggs. neot Spart until 12:00 eating lunch + preparing birds. Very windy up to 20+ mph from + difficult to work. Then broke camp & left refuge. Checked & measured three nests on way out. Caught adult shading young on nest #8. Then over to visit nest near airport. Tried to collect P as she flushed from nest - was unsuccessful. Measured nest + eggs. neot Then into (Harlingen) back to Brownsville. Bought some clothes+ groceries + took a motel ($15). Cleaned up & went out for supper. Temp 76-95°F. very windy during 8:00 - 16:00. Wind during most of night while other nights were still.
