One conspicuous in brush on S side of road calling red-dick - - - or vet-it - - - - over and over - song to NE and slightly farther E. I watched calling bird as it moved thru white-berbed shrub (accent on first, later on second phrase of call note.) Bird gave cleary audible 'Trip' whenever taking short flight (even a few inches) to new perch. Mate sighted in shrub to N, silent - caller moves into mesquite tree to S and I crossed road. - this pair near juniper-like shrub. The move pair which had answered now silent except for "location" notes - trip of one usually answered by softer 'tits' of mate. When I sighted birds, they were farther from me than I had supposed they would be (± 50 ft.) Exchange of vet vet calls farther to E - 2 other pairs engaged? Silence at 8:40 I moved along road to E a few yards after 8:50, then circled south and W toward fence, then along fence NE nearly to gate. Pair of tits in mesquite tree, one called see see see vet vet, inornatus-like then both gave vet vet calls and Bewick when chimed in with rasping notes. I was not sure for a moment
