WRENDERINGS
Progress Report
Fall 1999

How was our progress during the breeding season of 1999? In one word, phenomenal. Despite a dry winter followed by a cold spring being unfavorable for breeding of many land birds, our participants still got thorough results from many areas. I'm delighted to be able to report that the threshold has been cleared, with 50% of the number of species on the target list confirmed breeding, in the three squares with the longest target lists. In J12, Wild Animal Park (46 species confirmed of a target list of 91) we must recognize the herculean efforts of Debi and Dan Bylin, in M20, Cuyamaca Peak (47 confirmed of a target list of 88), those of Ann and Tom Keenan, and in K10, Lake Hodges (45 confirmed of a target list of 87), those of Dick Barber. This highest threshold goal has now been met in 47 more squares since the last issue of Wrenderings, bringing the total at this level to 117, 24% of all squares. Congratulations to...

With a total of 40 squares now at the "one-third confirmed" threshold plus the 117 at the "one-half confirmed" threshold 33% of all squares have now been covered very thoroughly. Many more squares are lurking just under our threshold goals. In 32 additional squares over 50% of the target number have already been confirmed breeding--most of these squares are just short of the 25-hours-in-the-field criterion for their threshold to be reached. In 39 more squares beyond this over 33% of the target number has been confirmed. In 108 squares in addition to the 157 over the thresholds over 90% of the target number has been identified as at least possibly breeding, 80-90% in 70 more. Thus over two-thirds of all squares have already been covered fairly well--an achievement well within where we should be halfway through the project. When you consider too that we have substantial data from 452 of all 479 squares I hope you will agree with me that our progress has been phenomenal.
