Or were these just two especially stubborn birds in a territorial dispute? This happens frequently right here on my deck where I put out the peanut butter for the birds. My "mockers" LOVE peanut butter. They come to feed on it, take beaks full back to their nesting mates and both parents take it to their young when the eggs hatch. They bring the fledglings here to feed. Since I have one pair of "boarders" that come from next door downhill and another pair that nest about 500 feet uphill at another neighbor's, the adults indulge in "food fights" just about every day during the "feeding seasons." The mockers generally go for the wild grapes and holly berries during the fall, but indulge in PB for the rest of the year. On deck also, the mourning doves, Eurasian collared doves, starlings, rock pigeons and even the cardinals go after each other in order to chase them away from the grain and sunflower seed. Often, the squirrels and chipmunks enter the frays as well. Watch your feeders if you wish to see some fights! It does seem curious that the goldfinches, house finches, chickadees, and titmice seem to get along peacefully on my thistle feeder, although the house sparrows will go to battle over the food there.
