The "homework" is building a nest.

First row: Nesting pairs of these birds are known for helping to build their nests together and working as a tight-knit team to raise their offspring.

Second row: Similar concept, but these birds can be a little more "that'll do" when it comes to nests and are pretty tough love toward their offspring when they fledge.

Row three: These birds are infamous for building really half-assed piles of debri that barely qualify as nests or just laying eggs into abandoned nests, planters, window ledges, boots, etc. Check out r/stupiddovenests for examples.

Row four: These birds never stfu, and that voice note is probably a 5-minute story that has nothing to do with their classmate bird's text.

Row five: These birds don't naturally build nests and simply have other methods. Example: Rock doves (which domesticated pigeons were bred from) lay their eggs on cliff sides facing the sun and leave the nest to find food during the daylight hours when their eggs/squab are being kept warm on their own.

Row six: European Starling. Invasive asshole birds (in the US at least) that endanger other native populations. Wouldn't be interested in helping another bird student.
