    Opus, (mostly) Moroccan subspecies of Thekla's Lark

    Yes, Thekla’s can show a P1 shorter than the greater coverts, but a maximum of 2 mm shorter. Obviously it’s hard to judge exactly what the difference is here, but it looks substantial and likely more than 2 mm.

    Opus, (mostly) Moroccan subspecies of Thekla's Lark

    P1 is substantially shorter than the primary coverts on the first one too - very much better for Crested lark.
