Why do birds break their eggs if you touch them?

Answered by Douglas Hiatt

Let me start by saying that birds do not break their eggs if you touch them. This is a common misconception that many people believe, but it’s simply not true. Birds have a natural instinct to care for and protect their eggs, and they will not abandon them just because a human touched them.

I have personal experience with this myth, as I have worked with birds for many years. I have handled countless eggs and nests, and I can assure you that the birds did not abandon their eggs because of my presence. In fact, most birds are quite tolerant of human interaction and will continue to care for their eggs even if they are disturbed.

However, it is important to note that excessive disturbance or handling of the nest can cause birds to feel threatened and potentially abandon their eggs. Birds rely on their nests as a safe place to rear their young, and if they feel that the nest is no longer secure, they may choose to leave.

For example, if you repeatedly disturb a nest box by constantly checking on the eggs or handling them, the birds may become stressed and feel that their nest is not safe. This could lead to them abandoning the eggs in search of a more secure location.

In my experience, it is best to minimize disturbance to nesting birds as much as possible. If you come across a nest with eggs in it, try to observe from a distance and avoid handling the eggs or nest. If you need to move the eggs for any reason, such as if they are in a food bowl, it is best to carefully transfer them to a nest box or a similar safe location.

It is also worth mentioning that some bird species are more sensitive to disturbance than others. For example, cavity-nesting birds like bluebirds or chickadees may be more easily disturbed by human activity around their nest. On the other hand, birds that nest in more open areas, like robins or sparrows, may be more tolerant of human presence.

Birds will not break their eggs if you touch them. This is a myth that has been perpetuated over the years. However, it is important to respect nesting birds and minimize disturbance to their nests. By doing so, we can help ensure that they are able to successfully raise their young.
