Do pigeons (Columba livia) study for a test?

"In 4 experiments, the authors asked whether pigeons (Columba livia) would show metamemory by choosing to study a sample stimulus before taking a memory test...The findings of all of these experiments suggest the absence of metamemory in pigeons."

Procrastination by pigeons: preference for larger, more delayed work requirements.

"In three experiments, pigeons chose between alternatives that required the completion of a small ratio schedule early in the trial or a larger ratio schedule later in the trial... These experiments found clear evidence for "procrastination"--the choice of a larger but more delayed response requirement."
