Do babies swallows eat more than bugs?

Baby Swallows Are Like Any Other Bird, The Mother Bird Goes Out In Search of Food Apon Arrival The Babies Cheep To Tell The Mother Bird They Are Hungry She Regergatates (throws-up) The Insects She Has Predigested For Them... Swallows Build Their Nests From Spit and Mud Depending On The Type of Swallow...THEY DO NOT EAT MUD as A Food Source... The Ones That Live Around My House Eat The Crain Flies and May Flies Around The River...
