Thank you, Tweeters! Several replies and lots of good information. The plant in question is:
?Eriogonum heracleoides var. leucophaeum? or common name ?bractless parsnip-flower wild buckwheat?

I will be posting more plants and flowers as I try to learn something new. If anyone notices a mistake in passing, such as when looking at current bird photos, I would be pleased to be corrected.
