Backing up records from “unsafe” dates

A week or so ago, I provided two rules of thumb to reduce confusion over the use of safe dates:

1. If you are unsure whether to submit a record, do so.
2. Always submit any record that confirms breeding (i.e., warrants a 2-letter code).

The second rule has a firm basis in the way we will use the atlas data – anything that is confirmed is a solid record no matter what.  The first rule, however, simply defers the decision of what to include to us during the data management phase of the project.  This is good in that it means we can standardize what gets included and what does not, but we still have to decide when a record is counted as breeding evidence.

Which species have been confirmed?

Yesterday, I pointed out that evidence for confirmed breeding by any species should be submitted to the atlas, even if we are not yet within that species’ “safe dates”.  In light of that recommendation, I thought it would be worthwhile to list the species for which we have already received confirmed records.  This list is growing every day – just this weekend I noticed a pair of chickadees excavating a nest hole in a dead tree stump in my backyard (see video here).

Nesting hawks

One of the great things about living in Connecticut is the wealth of experience in the birding community.  The atlas team is taking advantage of that expertise not only to help us gather data, but also to provide insights to help volunteers become better atlasers.  Here, Connecticut Warbler editor and long-time birder, Greg Hanisek provides tips on finding evidence for breeding hawks in your block: Continue reading “Nesting hawks”

When is a pair of ducks really a pair of ducks?

Yesterday, a quick stop at a small pond in Mansfield turned up 2 gadwalls (a male and a female), 5 green-winged teals (3 males, 2 females), and a dozen mallards. The gadwalls were swimming around together, and one of the female teals was sitting close to one of the males. Given this observation, it would be tempting to report both species with breeding code P (pair) to the atlas project. Continue reading “When is a pair of ducks really a pair of ducks?”

Nesting ravens

Although it is too soon to begin surveying atlas blocks in earnest, a few species have begun to nest and atlas data have started to flow in.  For example, last weekend I saw a common raven fly across the Merritt Parkway in Orange (block 94F) with a stick in its beak – carrying nest material (atlas code CN).  I was a little surprised about the location, but I checked with local birder Frank Gallo who confirmed that there is pair that nests on a cell tower nearby.
