Last week seem to have been the peak migration of Yellow-rumped Warblers which have now reached a new season record (780) at Albert Creek. Towards the end of the week other Neotropical migrants, primarily Wilson’s and Blackpoll Warblers, arrived in good numbers. More species arrived early this week including Brown-headed Cowbird, Chipping Sparrow and Tennessee Warbler, the bringer of summer, as we call it here at Albert Creek. Two Olive-sided Flycatchers banded over the weekend were enjoyed by many as we have been having lots of fun and qualified help lately. A big thanks for everyone who have been helping out!

McIntyre Marsh - May 14 to 20

The past week at McIntyre Marsh has seen a transition from primarily sparrows to warblers. A few weeks ago, the marsh was filled with songs of White-crowned Sparrows and American Tree Sparrows. Now, the morning chorus is filled with the rolling witchy witchy witchy of Common Yellowthroats and the che che che che of Wilson's Warblers. New arrivals this week included Yellow Warbler (18 May), Common Yellowthroat (18 May) and Blackpoll Warbler (20 May). Some other banding highlights included an Olive-sided Flycatcher (15 May), a Belted Kingfisher (18 May) and 3 Wilson's Snipe throughout the week. Although not banded, a male Townsend's Warbler was observed/heard (its song a zizle zizle plink plink) and photographed on May 14th.

Albert Creek Update - May 6 to 11

This week Albert Creek was closed for four days due to personnel constraints. We returned into the action on Monday the May 10th.

It appears that the timing of the four day gap was perfect as there has been very little passerine movement lately. The banding totals for May 10 and 11 were 23 and 26, respectively. Yellow-rumped Warbler has been the most numerous species together with some late Ruby-crowned Kinglets and White-crowned Sparrows and early Orange-crowned Warblers. Northern Waterthrush and Wilson’s Warbler were new species for the spring.

Outside the nets the most notable change has been the appearance of shorebirds. Both Greater and Lesser Yellowlegs are now frequenting the area and small flocks of various species, including Solitary and Pectoral Sandpipers, have been seen flying over the site. A Swamp Sparrow is singing in the marsh and Tree Swallows have found the nest boxes.

McIntyre Marsh - May 8

The bird traffic through the marsh was somewhat reduced today in comparison to last weekend. Although the day's banding total was not very high (28 birds), there was a good variety of species including two new species for the season; Wilson's Warbler and Wilson's Snipe. The number of White-crowned Sparrows have dropped off substantially, but the numbers of Savannah Sparrow have increased. In fact, this was the top species banded today with 11 banded.

The station will be open again tomorrow (Sunday) morning from 7am to noon.

McIntyre Marsh Update - May 1 to 2

This past weekend was very busy at the marsh. The sparrows arrived in droves and kept us very busy extracting and banding. Fortunately, there were a number of helpers onhand and even more visitors who were able to see how a banding station operates when very busy. Some highlights from the weekend included the first Orange-crowned Warbler on the 2nd. Other new species included a Varied Thrush and a small number of Violet-green Swallows on the 2nd, these species have been at the site for a few weeks but had avoided the nets until this point.
White-crowned Sparrows were althroughout the site on both days and were the number one species, with 95 individuals banded. Other bird banded this week included; Myrtle Warbler (42), Slate-colored Junco (24), Fox Sparrow (17), Lincoln's Sparrow (13), American Tree Sparrow (12), Golden-crowned Sparrow (8), Savannah Sparrow (7), Violet-green Swallow (5), American Robin (5), Ruby-crowned Kinglet (4), Black-capped Chickadee (2), Varied Thrush (1) and Orange-crowned Sparrow (1).....grand total = 236 birds.

Some photos below include (in order); Savannah Sparrow, Orange-crowned Warbler, Myrtle Warbler, Golden-crowned Sparrow, American Robin, Violet-green Swallow and Varied Thrush.

Albert Creek Update - 28 Apr to 4 May

This post was written by Albert Creek volunteer bander Gwen Baluss, from Juneau, Alaska.



This week was characterized by variable spring weather, and good numbers of sparrows.
Highlights included a group of about 500 Sandhill cranes over the station on 4-29. Three
Rusty Blackbirds were captured on 4-29. April 30 brought many White-crowned and Fox Sparrows and some Lincoln’s and Savannah Sparrows, as well as Myrtle Warblers. It was also the first note of chorusing wood frogs. The weather was exceptionally nice and warm. But it rained on May 1, the day of the first White-throated sparrow song.


I arrived on May 2 to a cool cloudy day with a steady migration (85 birds banded) of mostly sparrows. We were excited to catch the first Hammond’s flycatcher, an early long-distance migrant. On May 2 the fickle nature of spring revealed a steady snow, so we didn’t band. It cleared beautifully overnight, but on the morning of May 4 we faced a temperature of -10 C and icy nets. Also, the migrants had clearly moved out, and as the day warmed we banded mostly recaptures.

We are pleased to report that the Barred Owl continues to be on site and was hooting at 12 p.m. on May 5.

Our international team of banders and assistants included:

Ted Murphy-Kelly, Whitehorse
Jukka Jantunen, migrating with the birds throughout the Yukon
Sarah Davidson, Haines Junction
Mario Benassi, Haines, AK
Pam Randles, Haines, AK
Manie Cooke, Watson Lake
Susan Drury, Watson Lake
Jessica Condon, Watson Lake
Gwen Baluss, Juneau, AK



Banding totals from the week included; Ruby-crowned Kinglet (7), Orange-crowned Warbler (6), Myrtle Warbler (80), American Tree Sparrow (28), Fox Sparrow (93), Lincoln's Sparrow (8), White-crowned Sparrow (96), Slate-colored Junco (16), Yellow-bellied Sapsucker (1), Black-capped Chickadee (1), American Robin (3), Savannah Sparrow (5), Rusty Blackbird (3), Common Redpoll (23), Boreal CHickadee (1) and Hammond's Flycatcher (1)......grand total = 373.

The photo below is Albert Creek's first Hammond's Flycatcher of the year !
