This may have been partly a leftover from the Victorian fascination with egg collecting (the infamous passion known as oology), but probably more from people’s burgeoning interest in the nests and eggs found in their gardens and fields, gateway artifacts to a newer hobby called birdwatching.

One interesting paper argues that contrary to what might seem logical, cuckoos do not aim to lay eggs specifically into the nests of those parrotbills whose egg color and pattern match their own. The rationale includes the speed of the laying (too fast to check for color matches) and the low number of egg-laying attempts (i.e.,

Here are three excellent but very different children’s books I enjoyed this year (two were published in 2013, one in 2011). They cut down the trees the parrots used for nesting and brought black rats, who ate their eggs, and honeybees who swarmed into their nests, and by 1937 there were only about 2,000 Puerto Rican Parrots left.
