Why Do Birds Abandon Their Nests With Eggs (8 Reasons)

Many people think that birds abandon their nests when the eggs are hatched, but this is not always the case. Some birds may abandon their nests when they sense danger or when they cannot find food. Other times, a bird may simply be too busy nesting to stay around and protect its eggs.

8 Reasons Why Birds Abandon Their Nests With Eggs

Bird abandonment is most common among birds that have dependent young.

It has been found that the most likely bird species to abandon their nests are songbirds since they have a highly developed sense of parental care and are not able to survive on their own after leaving the nest.

The reasons why birds abandon their nests are diverse and range from environmental factors to natural causes to human causes.

  1. Some birds abandon their nests because they are not able to build another nest or because their previous nest was destroyed.
  2. Other birds abandon their nests because they have young that need to be fed and protected.
  3. Some birds abandon their nests because they are migrating and do not have time to rebuild the nest.
  4. Inclement weather can cause birds to abandon their nests.
  5. Chick mortality rates can be high in abandoned nests.
  6. Nest predators can destroy eggs and chicks in abandoned nests.
  7. Some bird species are more likely to abandon their nests than others.
  8. Research has shown that most birds abandon their nests soon after hatching, with the exception of some songbirds. 

The Effect of a Bird Abandoning Its Nest With Eggs

The effect of a bird abandoning its nest with eggs can be both devastating and hilarious. In some cases, the eggs will hatch and the birds will raise young without their parents.

In other cases, the eggs may not hatch and the birds will starve to death. Regardless of the outcome, the abandoned nest is a striking sight.

How Long Can Bird Eggs Be Left Unattended

The truth is, that most people don’t know how long eggs can be left unattended.

The longer the egg is left unattended, the greater the chance of it being contaminated with bacteria and/or fungi. The lifespan of a bird egg can vary depending on the species but is typically around 24 days.

In the wild, most eggs are left unattended for about 12 to 16 hours during the day so that the parents can feed their young.

However, there are some people who believe that leaving eggs unattended for more than 24 hours can be harmful to the bird’s health.

How Long Can a Bird Egg Live Without Warmth

Most bird eggs are laid in nests that are maintained at a warm temperature. Some birds, such as the American Goldfinch, will incubate their eggs for up to 12 days without any warmth.

On the other hand, some birds, such as the House Sparrow, will incubate their eggs for only four days before abandoning them.

If the egg is kept at a temperature between 35 and 40 degrees Fahrenheit, it should be able to last up to six weeks. Beyond that, the egg’s chances of survival diminish significantly.

What to Do With Abandoned Bird Eggs

If you find an abandoned bird egg and willing to preserve it, then a few things you can do with it.

First, if the egg is clean and free of dirt or other debris, you can place it in a plastic bag and store it in a cool, dry place.

You can also leave the egg where it is found and wait for the mother bird to return. Alternatively, you can break the egg and release the chick into the wild. However, if you do this, make sure you clean the egg first.

You can also use the egg to start a new nest by using it as a model or drawing out the shape of a nest or eggs on paper. But be careful not to damage the shell while doing this.

How Do I Know if a Bird’s Nest Is Abandoned?

When you see a bird nest, there is a good chance that the parents have departed. This is easy to determine by looking for the following: –

One way to determine if a bird’s nest is abandoned is to look for any indications that the birds have left. This could include destroyed eggs or nests, vegetation that has grown into or around the nest, and a lack of activity from the birds.

The nest is empty and no eggs or young are present. The surrounding area is free of debris, which would indicate that the parents were removing all of the waste from the nest.

There may be a few broken twigs nearby as if the birds were trying to rebuild the nest.

If you are not able to determine whether or not the nest is abandoned, you can try to get close enough to see if any of the birds are inside.

If none of these methods work, you may need to contact a wildlife expert.
