  • Advanced theropods like the maniraptorans featured high porosity eggshells, suggesting that they laid and incubated their eggs in open nests in a similar fashion as their most closely related living birds. (ucalgary.ca)

(wikipedia.org)
  • hence it happens that, while all the other birds and beasts avoid it, with the trochilus it lives at peace, since it owes much to that bird: for the crocodile, when he leaves the water and comes out upon the land, is in the habit of lying with his mouth wide open, facing the western breeze: at such times the trochilus goes into his mouth and devours the leeches. (wikipedia.org)
