Tallywhacking Birds

In the world of field biology, a tallywhacker—as it has come to be affectionately and universally known to those who have had reason to use it—is a simple, hand-held mechanical device for counting things. Technically, it is known as a tally counter.

In my days of conducting seabird surveys in coastal Alaska some 30 years ago, the tallywhacker was an indispensable piece of field gear. Armed with a tallywhacker or two and a pair of binoculars, observers would, depending on the situation, (a) sit in a boat below a colony of cliff-nesting seabirds or (b) position themselves at a vantage point above the cliff face where they had an unobstructed view of seabirds on the nesting ledges. Many of the colonies contained multiple species (cormorants, kittiwakes, and gulls), so the general procedure was to place a tallywhacker in the palm of each hand, scan a selected section of the cliff face with binoculars, and tally the number of attended nests. For example, one might keep track of cormorants on the left-hand tallywhacker and kittiwakes on the right-hand tallywhacker, while keeping a mental running total of gull nests. And so it went, slowly moving down the length of a colony one small section of cliff face at a time until all nests were accounted for.

Tallywhackers are useful for more than just counting seabirds. They are still commonly used, for example, to count salmon as they pass through weirs on their way to spawning grounds in Alaska.

[No Title]

Today is the first day in many that the sun has been out. It has been another month of rain! I decided since it was not raining I would take some trash out to the dumpster which is located at the back area of our retail store. It seems every time I do dump trash I see lots of birds back there, and I always tell them “go out front, there’s lots of food in the feeders for you”. The only ones who listen are the goldfinches, house finches and mourning doves. As I was walking back toward the front where our store is, I heard a bluebird singing. I looked up and on the top of the parking lot light was a male Eastern Bluebird. . . . [click here to read the rest of this entry, as originally posted by Debbie Lea on October 24, 2006]

The Big Island: Waipio Valley Birds

We ended up changing our flight from Oahu to the Big Island so we could have a full day of hiking and be able to set up camp before it got dark. It was pretty rough catching the 6:15am hotel shuttle to HNL (especially after being out really late) but it was worth it when we arrived on the Big Island

Unlike Oahu, the minute you leave the airport you are greeted with breathtaking views of volcanic lava flow. We picked up some groceries and then headed straight to the trailhead at Waipio Valley. . . . [click here to read the rest of this entry, as originally posted by Birdinggirl on April 18, 2007]
