Oriental Skylark
Alauda gulgula
Oriental skylarks range from 15.5–18 cm (6.1–7.1 in) long and 24–30 g (0.85–1.06 oz) weight. They have streaked, yellow-brown upper plumage, with white outer tail feathers and a short crest. Both sexes are similar. The subspecies vary subtly in size, bill length, and plumage tone, with A. g. inopinata being the largest and palest. A. g. coelivox has a longer bill, and A. g. wattersi is more heavily streaked above. The Oriental skylark differs from the Eurasian skylark in being smaller, with a longer, more pointed bill, and a shorter tail and wings.

Woodlark
Lullula arborea
This is a 13.5- to 15-cm-long bird, slightly smaller than the skylark being roughly 20% shorter. The woodlark is mainly brown above and pale below, but with a distinctive white superciliar meeting on the nape. It has a crest which is quite small and at most times inconspicuous. In flight it shows a short tail and short broad wings. The tail is tipped with white, but unlike the skylark, the tail sides and the rear edge of the wings are not edged with white.
