1WattHermit had taken some pictures, left at comments on eschaton one morning when I got online. I borrowed these purple finch from him.
* The Purple Finch feeds on flowers by crushing the base to get the nectar and leaving the upper flower undamaged. In a similar action, it often feeds on the seeds of fruits rather than the pulp.
* The decline of the Purple Finch in the East may be partly explained by competition with the introduced House Finch. In aggressive interactions, the House Finch nearly always wins. A population decline was noted with the introduction of the House Sparrow too, nearly 100 years earlier.
* Two subspecies of the Purple Finch are recognized, a Pacific Coast form and the more widespread form. The Pacific form differs by having a different wing shape and duller colors. The songs differ too, with Eastern birds singing a more leisurely series of warbles spanning a wider range of notes.
