The obvious ones are storms, high winds, and some types of human activity, such as removing shrubs or trees.īut sometimes it's because of natural bird behavior.ĭid you know that the common Cowbird does not build nests? Instead, they lay their eggs in the nest of other birds. Some of the reasons you may come across bird eggs on the ground or abandoned in the nest might surprise you. Why Bird Eggs are on the Ground or Abandoned This means instead of one egg not hatching, you are responsible for 4 to 6 eggs not hatching.Įxceptions for Purple Martins or birds of the same species do exist. Just because you may have Wrens nesting in a birdhouse does not mean they'll raise a Robin or Chickadee.įinding an egg that doesn't belong in the nest may cause abandonment of the entire nest. So What Can You Do When You Find A Bird Egg?ĭo not place a bird's egg in the nest of another bird. In some species, like Mourning Doves, the male helps with incubation. ![]() Sometimes the male will bring food for the female while she incubates. Keep in mind, she will leave the eggs from time to time to feed herself. When she lays the last or next to the last egg, incubation begins. Then she will leave to feed the rest of the day. Most songbirds lay 1 egg each day, usually in the early morning. Many birds do not begin incubation until all or most of the eggs are laid. Make sure if you come across a nest with eggs that they have been abandoned. The primary purpose of this page is to give you an understanding of why you should not attempt to hatch an abandoned bird egg.Īt first, it seems as though it should be a simple process of just keeping the egg warm until it hatches.īut as you can now understand, wild birds have a huge job getting their young from egg to fledgling. Most require a variety of insects delivered several times each hour of the day. The dietary needs of baby birds vary with species. This may cause them not to make it through their first winter.įeeding a nestling would require a commitment of 16 hours a day, 7 days a week, for 2 weeks on average. There is no way humans can teach them these survival skills. Once the young leave the nest, they continue to learn what to eat and what predators to watch out for from the adult birds. It doesn't take much rain, sun, or cold to damage an egg.Įven if you get the egg to hatched, the young nestling would still face a slim chance of survival. How long the egg has been left in the open can be a determining factor in whether the egg can hatch. Often leaving them because of harassment from other predators or adult birds attacking them. Predators often drop eggs or place them somewhere. When and where you find the bird egg can be significant in the eggs viability as well. The membrane inside may be damaged, causing harm to the embryo.Īs stated before, temperature plays a major part in whether an egg will hatch.Īn egg left to cool once the incubation process has been started can spell disaster for the egg. Most bird eggs you find will not be viable, and your time may be for nothing.Įggs are fragile, while there may not be any visible cracks on the eggshell, an egg dropped on the ground is most likely no longer a viable egg. Providing all these requirements is more than most people can do without specialized equipment. This varies between 25-60 percent, increasing to 70-80 percent for the last 3 days. Humidity is also important during incubation. Turning the egg to prevent overheating needs to be done several times daily throughout the incubation time. On average, an egg needs to have a constant temperature of 100 degrees Fahrenheit to hatch. It doesn't hurt to check with local Rehabbers just in case they will take on the challenge of incubating a wild bird egg. ![]() Most wildlife rehabilitators are loaded down caring for injured and orphaned animals and birds. Temperature, humidity, and turning of the egg all play a part in getting a bird from the egg to fly free in the wild. Hatching to fledgling is not as simple as it appears. If the species is not protected, we have advice on candling and hatching bird eggs in this article. With the exception (in the US) of European Starlings, House Sparrows, and Pigeons, any possession of eggs, feathers, nests, or birds would violate the Migratory Bird Treaty Act. Believe it or not, in some countries, wild bird eggs are sold to restaurants to be used in exotic dishes. ![]()
