HOT Western Bluebird Nestbox Monitoring - June 18th, 2017

Sunday 2017-06-18 (9am): The Bay Area is tucking into a heat wave, so we went a bit early to try to beat the heat. I am wishing we had thought to install shade baffles for these boxes, but this is being a learning experience. The "batchelor button" flowers have come into bloom, and the grasses are very tall. The two Red-tail hawk fledgings were perched on the nearby utility poles, and we were serenaded by their constant calls during our entire visit.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Box #1: A Tree Swallow exited the box as we approached, and there are now 5 perfectly white eggs inside. We added some ventilation holes along the top sides. This box may be advantageous in the warmer weather now, having some shade.

Box #1.

 

 

Box #2: Still empty. Some ventilation holes were added to the top and bottom.

Box #3: Still an abandoned nest. My Dad added some additional top ventilation holes.

Box #5. This box now has Tree Swallows in it -- and the adult did not leave during the nest check! She looked to be sitting on at least 2 eggs.

Box #6: Empty.

Box #7: No longer occupied (hopefully the last clutch of Tree Swallow fledged), so we cleaned out the nest box.

Box #8: There is another Tree Swallow nest underway in this box -- with 5 eggs now.

 Box #9: The Western Bluebirds have decided to use this box again, and there are now 4 blue eggs.

Box #10. Still unchanged, no eggs.

In addition to the Red-tails, this very large hawk was perched closeby in the trees near the creek ... can anyone identify it??
