The dreaded Goat's-beard / Tragopogon dubius

(Note to self: this is my main photo posted today, i.e. the very last photo uploaded. Let me know if you see my photos posted in a different order - thanks).

The dreaded Goat's-beard, a highly invasive, non-native plant that has spread (and keeps spreading, despite attempts to control it) in our natural areas in the city. Too bad, because both the beautiful flower and huge Dandelion-like seedhead are most attractive.

This photo was taken the day before yesterday, 15 June 2015, when I went on a morning birding walk with friends at Griffith Woods. All the birds we saw were so far away, so I mainly came home with a few photos of flowers. Just for my own memory, I'll add the leaders' list of the 39 bird species below.
