At the end of October the morning monitoring group began picking up and examining pellets at the burrows to confirm what the owls are eating. A trend of insects and not rodents has been established. Being next to agricultural fields, it was expected for rodents to dominate their diet. At first we wondered if the farmer was putting down a rodentcide. Greg Clark recently discovered a researcher, in the Imperial Valley where 70% of California’s burrowing owls reside, who found only .2 % of pellets contain rodents. His explanation is that the flood irrigation eliminates rodents. Maybe this is what is happening here as well.
Now onto the owls themselves. 90X is her usual, confident self residing at #50, although of late she can be seen all the way down to #37 in the afternoon. This is due to the fact, I surmise, that 88X has not been on site since 1/9 and #37-46 was her “territory”. No signs of predation in the park this time as was the case with the last two owls. The female of the local pair at #15-16 has not been seen since 1/9 either but because she is so secretive and because it has been so cold I’m not completely convinced she still is not there. The really AWESOME news is the release site local owl who I had started to suspect was male has joined 90X at #49-50. Last week a regular park walker and the evening monitoring group saw them together at #50. Courting behavior was going on and the male has been named Whitebeard. (He really extends his white chin feathers very long when doing a courting display). This morning we watched Whitebeard come out of #49 and 90X out of #50. If you go out to see them Whitebeard flies easily if approached too close.
