Certhilauda subcoronata
The Karoo Long-billed Lark (*Certhilauda subcoronata*) is a charismatic avian resident of Southern Africa's arid and semi-arid landscapes. Measuring 17-20 cm in length and weighing 35-47g, its most distinctive feature is its remarkably long, slender, and decurved (downcurved) bill, which can be up to 40% of its head length, perfectly adapted for probing.
