Botteri's Sparrow
Peucaea botterii
Rather large sparrow with flat head and long bill. Dull brownish overall with darker streaks on back; subtle head pattern with slightly darker crown and eyeline. Primarily a Mexican species with two populations, both of which barely enter the U.S.; western birds brighter than eastern birds. Prefers grasslands with some shrubs. Shy, but perches conspicuously when singing. Similar to Cassin's Sparrow; note flatter head, longer bill, lack of eyering, and voice. Gives a series of sharp varied chips and a fast trill; much different than Cassin's sweet song.

Rufous-bellied Thrush
Turdus rufiventris
Large thrush found commonly in open woodlands, savannas, agricultural areas, urban parks, gardens where it spends a lot of time foraging on the ground. It has an olive-brown back and breast with an orange belly and a paler streaked throat. Note the yellow eyering. The song, which varies among regions, is usually long and quite monotonous.
Southern Emuwren
Stipiturus malachurus
A tiny, buff-brown bird with an enormously long tail. Tail is much longer and far more spindly than that of fairywrens. Females have dark streaks on the crown and back and are warm buffy-brown underneath. Males are similar, except they have a sky-blue throat. Typically very shy, they live in coastal heathland in southern Australia and are unlikely to be seen unless you are actively looking for them.
Gray-rumped Swiftlet
Collocalia marginata
A small, common swiftlet found over a variety of habitats, even human habitation. Gray below with some dark speckling. Black above with blue gloss, a pale band on the rump with some streaks, and a square tail that is dark under the base. Similar to Pygmy Swiftlet, but Gray-rumped is slightly larger and has a less demarcated rump band. Paler below than Germain’s. Does not echolocate, so chooses well-lit nesting sites. Usually silent, but gives a throaty “churr” near nesting site.
