Migration Monitoring
April 17th, 2007

It was another cool, raw day that found most passerine migrants at Ruthven staying put. Like yesterday, there were many more retraps – 3.5:1 as a matter of fact. I like Juncos but….enough is enough. I’d like to handle something different (and new) for a change.

There were a couple of large (50+) flocks of Double-crested Cormaorants going up the river and a solitary Common Loon headed north up very high. Other than that it was an unremarkable day.

Banded 10:
1 White-breasted nuthatch
5 Golden-crowned Kinglets
2 Song Sparrows
1 Dark-eyed Junco
1 Red-winged Blackbird

Retrapped 35:
1 Mourning Dove
1 Hairy Woodpecker
1 Downy Woodpecker
3 Black-capped Chickadees
2 White-breasted Nuthatches
1 Brown Creeper
4 Golden-crowned Kinglets
1 Song Sparrow
19 Dark-eyed Juncos
2 American Goldfinches

Estimated Totals: 42 species

  1. You sound like you’re getting depressed as a result of the lack of variety in bird species around. I don’t think Ruthven has antidepressants in its budget, so hopefully the migration will be back into full swing after the upcoming spurt of nice weather.

    I had two Myrtle Warblers in my backyard again on Saturday, along with a Caspian Tern.

  2. I had Caspian Terns and Black-Crowned Night Herons in Hamilton on Monday. Still lots of juncos there too though.
