I don't remember the weather forecast saying that we would be getting snow today, 28 October 2016 - I'm sure it only said rain. Anyway, it's snowing again this morning, with a temperature of 0°C (32°F) and windchill -2°C (28°F). Usually, I don't have three long day outings within five days, except during the Christmas Bird Counts, but two days ago, I was lucky enough to go with friends, Shirley and Anne, for a day's outing SW and SE of the city. We had a very early start, 7:00 am, and drove west of the city to start with, driving to the far end of Elbow Falls Trail (Highway 66). While at Elbow Falls, we saw a pair of American Dippers flying from rock to rock. They were vocalizing, too, which I had never heard before. Though there seemed to be very few birds to be seen all day, we were so lucky to see a total of four Moose - two at each of two different locations SW of the city. It is always nice to see a Moose, and to see four in one day was a real treat. The second two were fairly young ones, and I took this quick shot while photographing these youngsters. From Elbow Falls Trail, we drove down through the Millarville area and finally ended up east of High River. We found one of the Great Horned Owls that everyone had been following earlier in the year, along with a nearby little American Tree Sparrow. We did see a few Hawks, including a Rough-legged Hawk on a hay bale and a very dark morph Hawk later in the day. A great day, ladies - thank you so much for inviting me along and thanks so much, Shirley, for driving! Greatly appreciated. So glad we didn't have today's weather instead!

Another photo from the archives - again, I was looking for something green for today, St. Patrick's Day. Photographed this Lichen at the Perrenoud Natural Area, NW of Cochrane, on 18 June 2010.

The pale green, more "feathery" Lichen growing from this branch is an Usnea species. Not sure what the darker Lichen is. Found growing in the forest at Brown-Lowery Provincial Park on 13th November. "Usnea is the generic and scientific name for several species of lichen in the family Parmeliaceae, that generally grow hanging from tree branches, resembling grey or greenish hair. It is sometimes referred to commonly as Old Man's Beard, Beard Lichen, or Treemoss. Usnea grows all over the world. Like other lichens it is a symbiosis of a fungus and an alga. The fungus belongs to the division Ascomycota, while the alga is a member of the division Chlorophyta. Usnea has been used medicinally for at least 1000 years. Usnic acid (C18H16O7), a potent antibiotic and antifungal agent is found in most species. This, combined with the hairlike structure of the lichen, means that Usnea lent itself well to treating surface wounds when sterile gauze and modern antibiotics were unavailable. It is also edible and high in vitamin C." From Wikipedia.
