Looking down ...
.
A different feeding pattern today [17th] possibly because it was showering with rain or because the squirrel found the "Official" squirrel feeder in another area last night and wasn't quite as needy.

first visit [one image] at 06:43:47
second visit [one image] at 07:22:05
third visit [five images] between 07:24:18 to 07:30:53
fourth visit [three images] between 07:37:50 and 07:40:39

So, the second to fourth visit was just under 20 minutes in total.
But the squirrel could have been on the lower part of the wire peanut feeder, and so out of the trail cam's view at other times.
