This Week at Hilton Pond: “Confusing Fall . . . Composites”

Send to Kindle

Posted on 4 October 2011 by Bill Hilton Jr.

Birders have their "confusing fall warblers" and wildflower watchers their DYCs, which we prefer to call "Confusing Fall . . . Composites." The latest installment of "This Week at Hilton Pond" attempts to identify some of the baffling assortment of similar-looking asters and sunflowers that crop up along roadsides each autumn. To view our colorful up-close images of fall flora, please visit the photo essay for 15-30 Sep 2011 at http://www.hiltonpond.org/ThisWeek110915.html

While there, don't forget to scroll down for a list of birds banded or recaptured during the period; a miscellaneous nature note; and acknowledgement for several donors who've been kind enough to support Hilton Pond Center and Operation RubyThroat in recent weeks.

The deadline to sign up for our November 2011 hummingbird expedition to Costa Rica is just three weeks away. There are a few slots left for what is certain to be an enjoyable and unforgettable Neotropical experience. (Links to info for this trip--and the ones on tap for 2012--follow this week's photo essay.)

Happy Nature Watching!

Figure 1. Bidens polylepis, the Bearded Tickseed Sunflower (above), is just one of the many, many, many confusing composite flowers that appear on roadsides and in open places each autumn.
