Nest-site selection may affect nest predation rates, In this paper we
analyse nest-site habitat selection in the Thekla and Lesser Short-toe
d larks, and compare the habitats of successful and predated nests, Bo
th species have a preference for safe sites, At present, however, ther
e are not habitat differences between successful and predated nests, T
his is probably because nest predation has acted as an extremely high
selective pressure on ground nesting steppe birds, We may thus assume
that nest placements which facilitate predation must have been elimina
ted by this pressure in evolutive time.
