Had breakfast & then I went off to record Bridled Sparrow vocalizations. Spent until 0830 recording. Was able to get some songs from a lone ♂ uphill from the highway. Then found 2 pairs with adjacent territories + obtained some poor recordings of the chatter duet (See species acct.). Then spent from 900-1200 watching several pairs of Bridled Sparrows. Most of time watched foraging by pair which had a full grown young which they fed at least twice. Began to rain about 1215 + rained intermittently all afternoon. Spent afternoon preparing specimens + then went out to collect again only to get caught in a downpour. Fixed best so as to minimize leaks & forgot. Had supper after writing notes + to bed at 2000
