Descriptio

Threskiornithinis sunt rostra decurvata, et plerumque in gregibus vescuntur, cibum in luto petentes, saepissime crustacea. Monogamae et territorii zelotypae sunt cum nidificant et vescuntur.^[3] Plurimae in arboribus nidificant, saepe cum plataleinis et ardeidis. Omnes species exstantes volare possunt, sed duo genera exstincta volatu carebant: Apteribis in Insulis Havaianis et Xenicibis in Iamaica.^[3]
