Before very long, and while the first squirrel was a small distance away burying something, another squirrel started nosing around the lawn and approached the plate almost right away. (Grey squirrels have a keen sense of smell.) The first squirrel charged over and chased the newcomer away from the plate. Naturally enough the interloper gave the plate another try, and was chased away even more aggressively. In fact, the first squirrel made a decided effort to run the newcomer right out of the backyard altogether!
If this seems a little mean, it was made worse by the fact that the first squirrel was very plump and looked strong and robust, whereas the other one was small and kind of thin. The thin one was no coward, however, and was determined to stay in our yard -- but it was forced to sit nearby and watch as the fat one stayed beside the plate and ate to its heart's content. Once or twice fatty would stray from the vicinity of the plate to bury something, then skinny would make his move, but fatty had eyes in the back of his head and would tear back to chase skinny away once more.
V. was having none of this and marched downstairs to get another plate which she took out onto the lawn. Fatty and skinny scattered; even fatty was no match for V. Now we watched from upstairs again, with half the food on one plate and half on the other, as the two squirrels returned. The plates seemed to be so far apart that we figured skinny couldn't fail to get something to eat, but now fatty was even more determined and wouldn't let skinny near either plate.
Things got uglier still when a scuffle broke out between the two of them and one of the plates was upset and the food spilled onto the lawn.
Ultimately, however, skinny missed out entirely.
