WRENDERINGS
Progress Report
Winter 2000

We passed a major milestone this year in our coverage of the county in the breeding season: the number of squares where the threshold has been cleared is now 243 of 479—just over 50%. Enough electoral votes to declare victory! Now on to the landslide!

For reaching the most ambitious threshold, at least 50% of the target number of species for the square confirmed breeding, at least 90% of the target number found possibly breeding, and at least 25 observer-hours in the square, congratulations to our hard-working observers in 26 more squares since the last issue of Wrenderings.

The threshold has been met with all criteria except the number of confirmed nesting species is between 33% and 50% of the target in 12 more squares. Thanks to

Combined, the number of squares at the "one-half" and "one-third" confirmed thresholds is 293, 63%. And in 403 squares, a phenomenal 84% of the total, at least 90% of the target number of possibly breeding species has been recorded. Clearly, one more year's effort in the breeding season, if we maintain our momentum, will convert our victory into a landslide.

Let's turn now to the upcoming winter season. The winter threshold has been cleared in 157 squares, 33% of the total, and at least 90% of the target number of species has been recorded in 298 squares, 62% of the total. So our winter progress so far has been excellent too, but clearly we have a distance to go. In particular, don't forget that each square must be visited in at least three winters for its winter threshold to be met. Therefore, don't wait to the project's last year to cover your squares in which the threshold has not yet been met. If, as it looks so far, this coming winter will be the best for irregular, invasive species since 1996-1997, getting out this winter is all the more critical for our goals—not to mention for varied and interesting birding.
