It used to be said that there are three types of linguist:
- the ants, who patiently build, build, build;
- the crows, who just pick, pick, pick;
- the eagles, who soar on high, seeing further than all others.
But there is a fourth type:
- the cuckoos, who lay their productions in the nests of another theorist, thereby having them cared for as if legitimate offspring.
In biology, this is termed brood parasitism.
