Week 11 - The Weather Looks F(owl) This Week



Northern Flicker - Christian Kelly
October has arrived and we have entered into the final stretch of fall migration. Though overall banding totals were down at Pedder, Rocky Point saw an increase in numbers as we were able to get in a solid 6 days of banding without any closures due to military activity. The week started out on a bit of a low note as it was the first and only day we could not access the Rocky Point station, and wet weather shut things down at Pedder an hour after opening the nets. However, we were back to business at both stations the following day even though late day showers threatened to shut us down early again. The real excitement came on Oct 1st when we got to experience another post rain push of migrants at both stations. A whopping 135 birds were banded at Rocky this day, and was the second best day of the season for this station. A highlight for several of our volunteers was the banding of our first Red-shafted Flicker at Rocky. We had been observing a lot more of these stunning birds around the station in the last few days, and I think the collective will of our volunteers that day drove the bird into our nets.

Myrtle Warbler - Christian Kelly
Though most of our warbler species have vanished south at this point, we are seeing a huge increase in the number of Yellow-rumped Warblers observed (and banded). Well over 100 of these “butter-butts” were observed on a daily basis this week at Rocky, and we even managed to band 13 of them (9 of which were on our peak day on OCT 1st). Though it is sometimes hard to tell from a distance, there are two subspecies of Yellow-rumps that occur on the island: Audubon’s and Myrtle Warbler. At this point in the season the Myrtle subspecies seems to be the more common of the two, in fact all 13 of the birds we banded were Myrtle. During the breeding season it is much easier to distinguish the two warblers apart as their plumage is quite distinct, but as they make the switch into their basic plumage in the winter the differences between the two become much more subtle. But typically adult Myrtle Warbles will have a white throat, while the Audubon’s will have a yellow throat.

A string of sunny days mid week made for excellent conditions for raptor migration at the southern tip of the island. 11 species of Raptors were observed at Rocky Point on Oct 2nd (!), and Turkey Vulture numbers were at an all time high for the year with 594 individuals seen kettling over the station. Vulture numbers were consistently high throughout the week, but only of the Turkey variety ;-)

Love at first sight - Christian Kelly
On the other side of the gate Pedder was having a somewhat slower than usual, yet consistent week of banding. Once again the vast majority of birds banded this week were of the sparrow variety, though Hermit thrushes and Ruby-crowned Kinglets made up a good portion of the weekly totals. Though not a new bird for the station, I was very excited to have the opportunity to band our second Northern Pigmy Owl of the season! One or two NOPOs have been heard near the Pedder station most days this week, giving its characteristic rapid-fire hoots, and I was over the moon to have the chance to see one up close for the first time.

Speaking of owls! It continues to be another record smashing week for owl migration at RPBO. A jaw dropping 527 Northern Saw-whet Owls were banded between our two stations this week (332 at Rocky, and 195 at Pedder). We are now at a yearly total of 1301 NSWO banded this season!! This is a new record for the observatory, and we still have nearly a full month of owl migration left to go! Despite the bounty of this cute little feather babies were are still having a hard time filling volunteer shifts. Please sign up, we need you now more than ever!!

Other highlights from the week include:
  • First of the season Northern Saw-whet Owl banded during the day at Pedder
  • Orcas swimming through the channel at Rocky on Oct 4th
  • Lapland Longspur flyover at Rocky on Oct 5th
