Opportunistic breeding of the Citril FinchSerinus citrinella

Summary

In Catalonia the Citril Finch was found breeding from March to June in submediterranean and even mediterranean areas between 500 m and 1600 m a. s. l. This habitat contrasts with the subalpine breeding areas where breeding does not start until May/June. Breeding in submediterranean habitats coincides with high fructification of pines. Successive breeding in different areas allow the bird to extend the breeding season. The breeding in marginal areas seems to be more or less opportunistic and does not mean a range expansion.

Zusammenfassung

Zitronenzeisige brüten in Katalonien bei hoher Samenmast vonPinus auch in submediterranen und sogar mediterranen Bereichen zwischen 500 und 1600 m, und zwar von März bis Juni. In der höhergelegenen subalpinen Stufe begint die Brutzeit dagegen nicht vor Mai/Juni. Bruten in tiefen Lagen finden offenbar nicht statt, wenn diePinus-Samenmast gering ist. So scheint also die Besiedlung von tiefgelegenen Randarealen in Katalonien nichts mit einer Ausweitung des Brutareals zu tun zu haben, sondern eine opportunistische Nutzung günstigen Nahrungsanggebots zu sein, die zu einer Erhöhung der Jahresreproduktion durch sukzessive Bruten in unterschiedlichen Habitaten führen kann.
