RPBO Migration Banding as of September 11, 2015


Here is a list of species and numbers of new birds banded as of September 11, 2015 during our Passerine Migration Monitoring. Even though our two sites in Metchosin at Pedder Bay Marina and Rocky Point on Department of National Defense lands are only a few kilometers apart as the crow flies, it is interesting to note the difference in types and numbers of species banded as seen from the list below.

 
Rocky Point has banded over double the number of Pacific-slope Flycatchers and Willow Flycatchers compared to Pedder Bay. Pedder Bay has had double the number of Swainson’s Thrushes so far.

As far as warblers go, Rocky Point has had almost triple the number of Yellow Warblers and more Wilson’s Warblers as well. Pedder Bay has had higher numbers of Common Yellowthroat and Audubon’s Warblers. McGillivray’s and Orange-crowned Warbler numbers are about the same.

  
Spotted Towhees are not in great evidence at Rocky Point whereas they are seen and heard constantly at Pedder Bay. Many of our winter resident sparrows are just beginning to return at this point. And of course the Ruby-crowned Kinglets are beginning to trickle back.

As of September 11 Rocky Point has banded 48 different species and Pedder Bay 59. We have banded a total of 3132 birds so far.
