Siskin (Carduelis spinus)

The siskins love nyger seed and are very possessive about it: once they are on the feeder they will be quite aggressive in keeping their place against the advances of goldfinches and other siskins. Occasionally this will overflow into an amazing flight display: two birds flying almost vertically upwards while remaining beak-to-beak.
