Thekla Lark (Galerida theklae) Science Article 2
To describe the variation in laying date, clutch size, egg volume and hatching asynchrony of four lark species (Skylark Alauda arvensis, Short-toed Lark Calandrella brachydactyla, Thekla Lark Galerida theklae and Lesser Short-toed Lark Calandrella rufescens) and at two different time scales: between years (large-scale variation), and within seasons (short-scale variation). Location: Two climatically contrasting Mediterranean areas: Layna, located in the centre of the Iberian Peninsula and with a continental Mediterranean climate, and Cabo de Gata, located in the south-western Iberian Peninsula and with a semi-arid climate. Breeding Skylarks and Short-toed Larks occur in Layna, whereas breeding Thekla Larks and Lesser Short-toed Larks occur in Cabo de Gata.
