Northern Saw-whet Owls

It was a good migration year for our charming little owls and the human night owls who spent long hours in the dark! We banded a total of 1196 new owls – 781 at Rocky Point and 415 at Pedder Bay. It was only our second year banding owls for the full season at Pedder Bay and although we don’t catch as many owls there, it is open to the public which is a great asset. We had many visitors come to see what we do and I think everyone was delighted to see Saw-whets up close and personal! It is rare to see one in the wild as they are a nocturnal bird which migrates and hunts at night, so this is a special opportunity for the public.

Pedder Bay 2012 – 2015

This banding station has been in operation since 2012 and has already given us some fascinating data. It is wonderful that our younger enthusiasts can volunteer here and we can use it as a training opportunity for new volunteers. We can also accommodate banders and extractors from abroad who periodically come to participate with us. Since this site is publicly accessible it presents us with a number of exciting opportunities for public education and outreach. In addition to providing bird walks and other public activities focused on bird conservation, we now offer a more formalized field trip program for students in the Victoria area.

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.

As of September 11, 2015
