30 LLWOLF 1964 Journal July 7 Laguna Atascosa Wildlife Refuge, Cameron Co., Texas Up at 0530. Coyotes calling at 0500. Had breakfast & then drove around Refuge trying to locate colonies of Botteri Sparrow. First took tour of gunny range. Drove east on surfaced road then S. to sign pointing to shoreline drive. Followed road out to shore of Laguna Madre & drove the 2 miles along the shore. Found many Cassin Sparrows & a few Botteri (see species acct's). Then turned inland & back to surfaced road just N of Naval Auxiliary landing field. Then back to entrance. Route included areas of mesquite grassland, prickly pear + hackberry + scattered huisache + mesquite. Mesquite grassland 2 types - one with tall mesquite + non-bunch grass; the other with smaller trees + short bunch grass - prob. a salt grass. The Cassin Sparrows in more exotic prickly pear - hackberry & out into salt grass + mesquite. The Botteri Sparrows seemed limited to bunch grass-mesquite habitat. Then took lakeside tour around Laguna Atascosa. Found one colony of 6-8 pairs of Botteri where road comes closest to Laguna ~ 2 miles W of Refuge headquarters. Had heard several scattered odd just before this. Spent 20-25 minutes here recording & observing. Birds along here were also in bunch grass - short mesquite association. Drove on out to Rio Hondo East Road & crossed Upper Cayo Atascosa then thru gate just W of Cayo & back in along road beside Laguna + various ponds. Found Botteri in two places near gate - 60th times in habitat observations of migratory species of birds
