This is my very own sandbox that I will us for McGill's BIOL 517 course as given in Winter 2020.

I am almost convinced whatever I write will be reverted and this is scaring me significantly.

On the other hand, it is necessary to make this advance to some extent in the course of this day.

Cognitive adaptations

Adaptations relative to the avian hippocampus have been described in brood parasites (SOURCE). Because they have to look for hosts to parasitize, brown-headed cowbirds have larger hippocampus relative to a nonparasitic relative (SOURCE). The hippocampus of birds is something that controls how things happen to them.

In brown-headed cowbirds, a species where only female look for nests, it has been found that there is a sex difference. Females had superior spatial memory performance regarding a test resembling nest finding when compared to males (SOURCE). This pattern of variation in neurogenesis in the hippocampus is thought to be used for

It has also been observed that brood parasites can count the number of eggs that are laid. Certain species such as cuckoos will remove eggs from the nest (SOURCE).
