As the mournful crocodile

With sorrow snares relentless passengers.

Shakespeare, 2 Henry VI. act iii. sc. 1 (1591).

Crocodiles weep over the prey which they devour.

The crocodile will weep over a man’s head when he [it] hath devoured the body, and then he will eat up the head too.--Bullokar, English Expositor (1616).

Paul Lucas tells us that the hummingbird and lapwing enter fearlessly the crocodile’s mouth, and the creature never injures them, because they pick its teeth.--Voyage fait en 1714.

Crow. If a crow croaks an odd number of times, look out for foul weather; if an even number, it will be fine.

[The superstitious] listen in the morning whether the crow crieth even or odd, and by that token presage the weather.--Dr. Hall, Characters of Vertues and Vices, 87.

If a crow flies over a house and croaks thrice, it is a bad omen.--Ramesey, Elminthologia, 271 (1668).

If a crow flutters about a window and caws, it forbodes a death.
