A pair of wrens have a nest outside our window.  Four eggs hatched, but one baby bird grew very quickly until it seemed larger than the parents.  It hogged most of the food and finally left the nest.  The other three are very tiny and still feeding.  Could the larger baby have been another type of bird?
