It doesn't do to hold back. That could be the motto of the robin. His desire to be first to the food is based on sound principles and observation.

If you wait too long you may get nothing because others have different techniques and once established take everything. Hence the avidity.

So not much success in teaching table manners.  Tits seem more laid back but they simply approach the problem in another way. They look indifferent for a time then make a swift dive remaining at the site less than a second before making off.

Chaffinches are closer to the robin in their approach but less intensity while the blackbirds out here are far more wary of people than in the typical suburban garden.
