Coastal Miner vs Common Miner

Coastal Miner

Geositta peruviana

Small21 gShrubland

The coastal miner is a small member of its genus. It is 12 to 14.5 cm (4.7 to 5.7 in) long and weighs 16 to 19 g (0.56 to 0.67 oz). The sexes are alike. The nominate subspecies has pale brown upperparts with slightly paler uppertail coverts; the other two subspecies are a lighter pale sandy brown above. Their central pair of tail feathers are brown and sandy brown respectively. Voice: As of early 2023, xeno-canto had only three recordings of coastal miner vocalizations; the Cornell Lab of Ornithology's Macaulay Library had seven. The species sings "an unmusical pjee-aww" during its display flight. It also makes "a squeaky cueet" call.

Common Miner

Geositta cunicularia

Small29 gGrassland

The common miner is a medium-size member of its genus. It is 14 to 17 cm (5.5 to 6.7 in) long and weighs 20 to 34 g (0.71 to 1.2 oz). The sexes are alike. The nominate subspecies G. c. cunicularia has a pale brownish face with a wide whitish supercilium and a vague darker "moustache" and line behind the eye. It has a dull grayish brown crown and upperparts; the former has dark brown spots. Its uppertail coverts are dull grayish brown with pale brownish tips. Its tail feathers have buff-whitish bases and blackish ends with pale rufescent between them. Voice: The common miner sings during a display flight. The nominate subspecies's song is two notes sounding like "ta whit-ta whit" and its flight call is "a nasal 'dee-dijer' or 'er?' ". The other subspecies sing "a loud, shrill...'de-dirr-rr-rrr' " and their flight calls are "a high-pitched 'keep' or rich, sweet 'pip' ". All subspecies make trilled notes as well.
