Only select a sub-category....
  • These Vancouver Canada Geese are resident in the Juneau area.
  • The mated pairs will soon leave the local wetlands for nesting on places like Admiralty Island.
  • Later the subadults will leave and fly to remote areas in places like Glacier Bay for molting.
  • To learn about the habits of our local geese look at Waterfowl in Winter by Bob Armstrong and Marge Hermans
  • The male Pacific Wren usually builds more than one nest and the female chooses which one she wants.
  • Only the female incubates the eggs.
  • The female generally feeds nestlings more than male does, although the male’s contribution increases with older nestlings.
  • For good information on the Pacific Wren look at Toews, David P. L. and Darren E. Irwin. 2012. Pacific Wren (Troglodytes pacificus), The Birds of North America Online (A. Poole, Ed.). Ithaca: Cornell Lab of Ornithology; Retrieved from the Birds of North America Online: http://bna.birds.cornell.edu/bna/species/720
  • These authors write The species is unique among North American wrens in its association with old-growth forests. It uses old-growth structures (snags, root masses, downed trees, and the bases of large standing trees) for nesting, foraging, and roosting.
  • And the presence of Pacific Wrens is correlated with riparian areas enriched with salmon-derived nutrients.
  • I often observe them feeding on the blow fly maggots on salmon carcasses.
  • In the nest on my back porch at least two wrens are spending the night in the nest this winter (2017)
  • For good information about wrens look at Big presence in a tiny package by Mary Willson
  • This video shows the growth of Skunk Cabbage over a one month period.
  • To do this a short video was taken about every 3 days during the month of April in Juneau, Alaska.
  • Skunk Cabbage is one of our earliest blooming flowers often starting to grow through the snow.
  • The value of Pacific Herring as a food for other creatures is high.
  • This video is mean't as an introduction about the value of Pacific Herring for other creatures in Alaska.
  • For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released September 8, 2015 into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil can develop hidden heart defects that compromise their later survival, indicating that the spill may have had much greater impacts on spawning fish than previously recognized.
  • To view the results of this study look at Cardona, J. P. et al. Very low embryonic crude oil exposures cause lasting cardiac defects in salmon and herring.
  • This is a rare bird for Southeast Alaska and Uncommon to Rare in other regions of the State.
  • Nils Warnock, the Executive Director for Audubon Alaska, wrote in my Birds of Alaska book the following:
  • "There are 53 shorebird species and subspecies that regularly occur in Alaska; 24 percent are deemed vulnerable or declining. One of these vulnerable species is the Hudsonian Godwit, a bird that migrates all the way from southern Chile to breed in Alaska. In its journey from Alaska to the southern tip of South America it faces threats from warming summers at the breeding grounds, loss of water and wetlands in the Midwest, the effects of deforestation in the Amazon, to disturbance at its wintering grounds in South America."
  • This video is meant as an introduction to a discussion about the value of some creatures that sting us.
  • Think about their value as pollinators.
  • Think about the fact that they are important predators of pest insects.
  • Think about what eats Yellow Jackets.
  • Learn about the insects, such as flower flies, that mimic Yellow Jackets (at least one photo in the photo section shows a flower fly and yellow jacket next to each other).
