Nodding (Musk) Thistle / Carduus nutans

The large Nodding or Musk Thistle is my favourite species of Thistle. When I saw this one, it was obviously well past its prime. Unfortunately, this quite spectacular and beautiful species is on the list of Restricted, Noxious, and Nuisance Weeds In Alberta. It is a biennial that spreads rapidly by seed forming extremely dense stands, though when I have seen this species growing in several places within the city, there are usually only a few of them. However, if they are left ....

This photo was taken on 8 October 2015. Friend Sandy had asked if I wanted to go with her to join friends down at the Irrigation Canal in the city, for a birding walk. This was a long walk - three and a half hours - along both sides of the canal. It was a beautiful fall day with a lovely blue sky. Also, enough trees were still dressed in gold to give some colourful reflections in parts f the canal. The water level was very low, creating just a narrow strip of water with a wide mud bank on either side, that had attracted a number of Greater Yellowlegs and a single American Golden-plover juvenile. The latter was a new bird for me and, though I could only get a very distant, poor shot, I did post it on Flickr. To me, a juvenile American Golden Plover looks so similar to a juvenile Black-bellied Plover (from photos I've seen), but the ID for the bird we saw was given as American Golden-plover. Much of the time, there were pale, dead grasses in the background and this bird was almost invisible. Great camouflage.

We also saw several Hooded Mergansers there. I don't often see Hooded Mergansers and, when I do see one, it's always a long way away. They are quite spectacular ducks, especially the males, who have a crest at the back of their head and can raise this black and white "hood" or lower it.
