Here is one last diorama post, this time from a deciduous forest with, what appears to be cottonwoods or aspen stands and a Northern Flicker in the center, a Yellow-Bellied Sapsucker on the left and a snoozing flying squirrel in its den on the right. Of the three diorama posts, in my experience, this one is the most unrealistic. Winter is definitely woodpecker season, so it is quite easy to see this type of woodpecker abundance (multiple species in the same stand of trees). I have never, however, encountered multiple species of woodpeckers like this during any of the other seasons. As a matter of fact, my woodpecker track record during spring, summer and fall is atrocious. Of course, it could just be me…, I am sure the woodpeckers are there all year round, they just are better at hiding when there are leaves on the trees I guess.
Right by the parking lot at the south side of Elk Island National Park there was an energetic Yellow-bellied Sapsucker hard at work trying to drill holes in the posts of a widening fence. Sapsuckers are known for creating symmetrical rows with large number of shallow holes on trees in order to harvest tree sap. I wonder if it was working on the wooden fence by mistake (which clearly will not have many sap) or if it was looking for insects (which the fence posts may have). Sapsuckers can make a large number of holes in a single tree and there are known instances where trees are girdled by overly enterprising sapsuckers. The Yellow-bellied Sapsuckers is our only woodpeckers that migrate south in the winter.
Our last stop of the day during our Big Day of Birding tour with the Edmonton Nature Club was Big Knife Provincial Park about 2 hours drive south east of Edmonton. The whole gang went for a walk through the forest, which was a nice change as we had spent most of the day doing in the car. This small provincial park straddles the Big Knife Creek, named after a fight to the death between “Knife”, a member of the Blackfoot tribe, and “Big Man” of the Cree tribe. I have not been able to find out why there were fighting, but clearly it must have been something of great importance. During our nature walk we found 15 species of birds, including a bunch of firsts (first of the year and first in our life); including the Great Blue Heron (Ardea herodias), Broad-winged Hawk (Buteo platypterus), Eastern Phoebe (Sayornis phoebe), and the diminutive Golden-crowned Kinglet (Regulus satrapa). As we were leaving we came across a Yellow-bellied Sapsucker (Sphyrapicus varius, Life: #145 , AB Big Year: #96) hard at work drilling sap wells high up in a lattice of branches. Unlike other woodpeckers, Sapsuckers do not look for insects to eat in dead trees. Instead they make, and maintain, sap wells and use the sap as their main food source, just like humans utilize the sap from maple trees for maple syrup. These sap wells must be continuously maintained so that the sap continues to flow. It had a rather scruffy appearance, like someone that just rolled out of bed in the morning after a few days without showering. I have been told, however, that that’s how sapsuckers roll it.
