For 2012, breeding location of 150 pairs cachinnans, of which 54 adults ringed and 158 pulli in 2012 (pers comm. Łukasz Bednarz).

Breeding bird trapped at the nest. Adult, with limited speckling in iris. Red orbital ring and gape. Red on upper mandible; faint black on the upper and faint black on the lower mandible. Yellow legs.
Deep white tongue on P10 (breaking the medial band, so merged with white tip = thayeri pattern and surprisingly, some sub-terminal black on P10), and broad black band on P5; no black spot on P4. P1 dropped; PMS=1.
