    For Totals so far, we have 30 nestings, 124 eggs laid, 108 hatched, and 90 new bluebirds in the air. We are missing reports from quite a few but as I mentioned elsewhere my internet has been down for more than a month and I am trying to catch up on posts to get additional data.

    Thank you all who have sent this data. It does show that we are doing a pretty good job of keeping the Bluebird population growing..

    Only 9 fledges out of my 12 nestbox Trail (2 boxes are for TRES) gives one an idea of just how much the mid-February freeze in states to our south (where blues winter over) resulted in the deaths due to snowfall and extended freeze.

    A neighbor (gave him nestbox and training) has an ideal yard location overlooking a park. He has consitently fledged 5-10 blues each year for the past ten years (Gilbertson PVC — plus mealworms). This year no blues no nest. He didn’t see even one bluebird all summer.

    Many Bluebird Trails whether with 10 or 100 boxes experienced a decline in EABL fledges from previous years. Not uncommon for a 70% decline in fledge counts by mid-June.

    Besides fewer bluebirds also a noticeable decline in robins (and Wrens). The deep freeze in Arkansas was one state that contributed to Minnesota’s decline in bluebird fledges … https://www.nwaonline.com/news/2021/mar/09/birds-took-hit-during-deep-freeze/

    Will post final EABL fledge counts for 2021 by reporting members of both BRPM(MN) and BRAW(WI) — usually posted by February. This will give an idea of just how significant the decline due to mid-February deep freeze where Minnesota’s Blues winter-over.
