Birds have many natural predators such as cats, snakes, foxes, raccoons and even larger birds such as hawks. In some cases if one parent is killed, the other parent will try to take over nest duties. However for most songbirds the males are not equipped to incubate eggs. Some species are very collaborative with the males helping gather food. If a male partner is killed, the female may judge that she cannot handle the workload of incubation and feeding on her own and give up the brood.
If you have nesting birds in your yard you may want to consider keeping your kitty indoors until the young have left the nest.
Which brings us to our next point. Most birds have a strong instinct to stick with their nest. But if they feel overly disturbed or harassed, they may give up and desert the nest. This disturbance could come from competing birds trying to get at the eggs, animal predators looking to raid the nest, or humans being too curious and getting too close for comfort.
Hatching eggs and raising babies is a lot of work! One bad encounter with a predator, even if they bird is successful in defending their nest, may be too much if they fear the predator will return.
Humans getting too close to the nest can also cause a lot of stress and make the birds give up, fearing the safety of their nest location has been compromised. Some species are more easily scared away than others. Also, younger birds who are having their first nesting season might be less experienced and more apt to desert a nest when scared. Do your part and steer clear of a nest if you spot one.
If you want to observe, view nests with binoculars from a safe distance. Depending on where the nest is built, this may mean avoiding a certain section of your yard for a few weeks, or only walking by minimally.
The birds will thank you. If a nest becomes infested with flies, ants or mites, it may be so unbearable and unhealthy for the parent sitting on the eggs that the nest is abandoned. Most of the time yes, the instinct to stay with the eggs is strong unless there is a lot of disturbance. Most bird eggs will remain healthy for up to two weeks before incubation starts. During this pre-incubation period, birds may leave the nest for long periods during the day. After incubation has begun, parents can still leave the nest but only for a maximum of approximately 30 minutes.
Eggs can be easily cracked, and jostling could damage the developing embryo. Newly hatched birds are equally vulnerable to injury, they are very fragile. Competing birds such as cowbirds and house sparrows may remove eggs from another birds nest. Adult birds are often aware if one of their eggs is infertile, and may remove it from the nest to make room for the others. A predator may have snatched the egg and dropped it. Squirrels, crows, blue jays, raccoons, foxes and snakes will nab eggs from a nest.
If you KNOW the egg fell out of a nest and can easily reach the nest location, you can carefully pick the egg up and put it back. Eggs are very fragile, use extremely light handling. If you do this and the egg shows up on the ground again, leave it. The adult is removing it for a reason.
Outside of the above scenario, it is best to just leave them alone. Fallen eggs are most likely broken, or the developing chick inside has sustained injuries from falling, or the egg has been out of the nest for too long to maintain its proper temperature. In all cases the chance of survival for the chick are basically zero.
Color, weight, smell and temperature are all clues. If there is any sign of a crack or hole, the egg is not viable. It is otherwise illegal to possess eggs of a native bird under the Migratory Bird Act.
