WRENDERINGS
Progress Report
Winter 1999

Map of breeding data received
Black: Threshold cleared (50% of target list confirmed)
Dark gray: Threshold cleared (33% of target list confirmed)

Map of winter data received
Black: Threshold cleared (90% of target number and 25-hour criteria confirmed)
Dark gray: 90% of target number criterion only met

We've received data for the 1999 breeding season from many additional participants since the last issue of Wrenderings, over 10,000 more records. The threshold has been cleared, with 50% of the target number confirmed, in 14 more squares, bringing the total at this level to 131, 27% of the total. Congratulations to...

It's encouraging that most of our participants who clear the "one-third confirmed" threshold confirmed go on to clear the higher "one-half confirmed" threshold.

The number of adopted squares is holding steady at 342 or 71% of the total. If you're thinking about adopting another square, please peruse the map of adopted squares; there have been some changes since the last issue of Wrenderings. Some formerly adopted squares become "open" again when participants move or change jobs. Also, if an observer hasn't sent us anything for a while and hasn't responded to our attempts to contact him or her, we will "release" a square in the hope of its attracting a more active participant.

Thus we can't emphasize enough the importance of your sending us the data from your square regularly. Covering an area as large as San Diego County to the ambitious level at which we're aiming requires we manage our resources very carefully. We can afford to schedule blockbuster weekends or send field assistants only where they maximize the effectiveness of our coverage. Please help make us as efficient as possible by sending in any data still outstanding.
