K Dixon 1951 25. Parus atricristatus March 2. 4 mi. SE Rio Grande City, Starr Co., Texas mate in shrub adjacent. I shot one bird (# 471). Mate flew to tree to W 35 feet or so and kept moving and calling (calls not recorded) As I followed, this bird (# 472) a male, flew back to the precise spot where she had been perched when I took her. I collected the ot at that time. A few minutes later I followed a pair at the edge of the riverbottom (perhaps the pair I had shot at earlier in the mesquite 150 yards or so to N). One bird was calling si ver si vet vet and moving ahead to NW. Its mate lingered to forage along the way and I took her (# 473). I followed her mate, increasingly agitated (at each of response from her?) and felled him with a shot. The bird only wounded flew into a brush pile & I lost it. I saw no more twice in this area. thinned out, partly cleared and no more twicce in mesquite thickets to N. (See journal account) 7 miles by road E Rio Grande City Starr Co., Texas At 1:20 p.m. I heard call of a twicice and saw two together near the highway in brushy area of mesquite and such shrubs as Adolphia?, flat Opuntia etc. This dry hillside was at least 2 miles from the riverbottom.
