THE ORIGIN

June 28, 2007

Several years ago, I noticed a banded Steller's Jay sneaking kibble from our cat's food dish. Having no experience with bird studies, I wondered how and why that particular bird had been captured, and by whom. At that time, (before peanuts) jays were surprise visitors appearing on glorious, sunny days for brief encounters, stealing bits of food, then calling loudly from high branches of redwood trees.

Subsequently, I learned from my friend, Jeff Jacobsen, about Pia and Dr. Jeff Black's study of the "social system and ecological relationships that drive the distribution and dynamics of the local jay population" (Wildlife Department, Humboldt State University--see link below). Pia placed a feeder/trap at eye level outside my family room window where I could see the birds coming and going each day. I looked forward to watching their dazzling-blue plumage, jaunty crests, and trickster manners.

Each of us watching feeders have stories to tell about the relationships, habits, and unique characteristics of individual birds that frequent our places. I hope this blog will allow us to share our observations and images, as well as provide an opportunity to share our delight in these curious, smart, and at times, raucous birds. c.arnold

2160 Terrace/South Feeder

0090-0010
A still white sky, quiet morning other than a few chickadee/dee sounds, watching southward. Peanuts are placed to the very back of the trap with two piles, one each on the deck and bench below. Metal/Red-Green/Orange (my resident male) is waiting in the crabapple for peanuts along with his mate, Metal/Blue-Orange/Black and an unbanded bird. MB/OB has a very swollen left leg (mites) and holds it up, gingerly. Both of the resident pair are feeding on seeds, filling their gullets, then flying south.

Metal/Blue-Red/Green arrives, goes clear into the feeder (this will be an easy bird to trap) then flies southeast. Next, Metal/White -Black/White takes a peanut, perches above the feeder and carefully cracks the nut, placing the contents gently on the branch, taps into the nut, then wipes its beak. Resident female chases him/her, though mw/blackw is persistent. He comes back quickly, goes clear into the trap and I notice he's growing new tail feathers; they look worn. mr/gw arrives, eats his first peanut in the tree, then flies off SE.

MBlue/RG returns and shares the bench with the resident female, each taking a peanut and flying off. Resident female looks much older, grayer than MB/RG. Male begins calling, first cheep/cheep/cheep/cheep/cheep, than kwaaa/kwaaa. Metal/White-Red/Green comes, takes a peanut very quickly and flies off, southwest.

Fairly well developed pink-gaped juvenile arrives, takes a peanut off the bench, jumps down to the ground, then flies south.

Mw/rg returns, goes clear into the trap, drops a peanut to the ground, grabs one in his bill and flies westward.

Unbanded shopper, picks up/puts down, picks up/puts down.


Overall, relatively quiet morning.Purple/blue-metal/purple, a bird almost always here, not seen. After several seed trips, resident pair began choosing peanuts rather than seed. Two little chickadees busy in the tree. Lots of peanuts left as I end this observation.

Total Number of Birds: 7-8

Data Collecting

This information was copied from the website of Dr. Jeff Black, Humboldt State University Wildlife Department.

The data to include for each record:

  • Bird’s color code
  • Size of social group seen at the same time
  • Associates’ color codes (or if unbanded = UNB; or not determined = NOTD)
  • Number of times associates came within 3 meters of each other
  • Approximate time spent within 3 meter distance (e.g. 2 seconds, 15 sec, etc.)
  • Total time you watched the birds (e.g. 5 minutes, 10 min, etc.)
  • Time of day; start of observation (e.g. 1935)
  • Date (e.g. 9.30.99)
  • Location of observation (e.g. Rewood Bowl SW corner west bleachers. And state whether the bird was seen at a birdfeeder or in trees, etc)
  • Comments (e.g. deformed leg, feather tuft on back, etc.)
