Thistle seeds signal goldfinch nesting
Almost as ephemeral as the very breeze that carries them along, feathered thistle seeds sail an open sea over the Plaza meadow.
Soft. Delicate. Impermanent.
The American goldfinch (Carduelis tristis),
is the last bird to nest in the calendar year. They wait until the thistle seeds are borne with their filaments of fluffy plant down. The bright yellow songbirds line their bassinets with layers of white comfort like fresh-whipped meringue.
