For example, the Brown Honeyeater visits more than 300 different flowers. While females hatch from larger eggs and are initially heavier than their brothers, after ten days, the male chicks weigh almost 50% more than their sisters, as they receive a higher quantity and quality of prey from their parents ( source ). .”

These run the range from birds like Barnacle Goose and Little Egret, which are rare but do show up in North America every few years (actually, lately it’s been every year) to birds whose sightings in North America are so few that they’re legendary–Western Reef-Heron and Corn Crake are two examples.

The last example suggests the difficulty of making a clear distinction between an animal part and an animal product.
