44、 Y1112Handle with Care On average,a female condor lays only one egg every two yearswhich is one rare and significant egg for an endangered species!Even though each egg is vitally important to the survival of the species,a condor mother doesnt build a soft nest in which to lay her egg.She lays the eg

45、g right on the hard surface of a rocky cliff or cave floor.Condor parents are diligent about protecting the precious egg.After about fifty-six days,the chick begins to hatch.It can take up to a week to completely emerge from the egg.Both parents help feed the chick.They store food for the chick insi

46、de their throats,carry it back to the nest,and then pass the food from their bills to the chicks bill.As the chick eats and grows,its feathers gradually turn from gray to black.When the young bird is around six months old,its ready to fly.Condors have few predators and live long lives,usually about

47、sixty years.In the wild,the biggest threats are from falcons and eagles,which try to snatch condor eggs.Condors live longer in captive settings,such as zoos,where some have lived for more than seventy-five years.What Makes a Condor a Bird?What Makes a Condor a Bird?All birds have a backbone have fea

50、coastal areas,while others live in arid inland regions.Typical condor habitats include rocky canyons,gorges,deserts,cliffs,and mountains.All these landforms serve condors well since they prefer to perch in high places.Experts have recently discovered California condors settling high in the cavities
