Behavioral Tracking With Nest Stages

The most important thing to understand about these six phases is that bird nesting can be behaviorally monitored in phases.

While there are undoubtedly general guidelines regarding when birds should lay their eggs in any given region of the world, the precise dates can vary from year to year based on factors like temperature.

Therefore, the only surefire method to determine the exact time that birds are laying eggs is to closely monitor their behavior and search for these nesting stages.

Just keep in mind that birds lay their eggs between stages three and four.

Stage 6: Juvenile Fledglings

The nestlings are prepared to try out their wings after a few weeks. They resemble full-sized birds at this point, but their consciousness is still developing.

They still rely entirely on their parents, and their flying skills are not very good.

Adolescents will beg for food by flapping their wings and trailing their weary parents around.

Stage 2: Nest Building

Soon after they have paired up, the birds will decide where to start constructing their nest.

Occasionally, both the male

The main thing to look out for in this area is birds that are either regularly flying into certain sheltered spots or carrying small twigs or gathering mud.

It’s crucial to give the birds room and avoid disclosing the location of their nest to robbers such as crows or jays.

This is an excellent time of year to find a place to sit and observe any movement patterns from a distance.

Here’s a previous video I made that walks you through a few basic distance-finding techniques for bird nest location:

The birds are now very close to mating, so keep a close eye on them during the next few days and weeks.

After the nest is built, this is when mating occurs.

Before the females lay their eggs in the nest, their partner must fertilize them.

Additionally, laying eggs requires a lot of energy, so the actual mating

It can be difficult to witness mating birds, but if you watch silently for a long enough period of time, you will undoubtedly see one.

It may only take a few days or a week for all the eggs to be in the nest when I witness birds mating in the morning.

Though it’s a fairly subtle behavior, this is the precise moment in stage 3 right before stage 4 when the eggs are laid.

Seek indications that the birds have completed constructing their nest. This could be more noticeable to you as the absence of nest building that would have occurred in the days preceding

Additionally, keep an eye out for real mating behavior in the tree branches. The male & female might perch close together, intermittently chasing.

Now that the eggs are incubating, the parents are sitting atop the nest and regulating the temperature of the eggs.

They must keep nourishing themselves and avoiding predators while doing so.

Sometimes the parents will fly out to warn of some invading crows or get scared off the nest if you notice nest robbers in the area at this time. They will quickly return to the nest if you keep an eye on them.

The parents may have to start over if the eggs become too cold or if a nest robber finds the location of the nest.

Keep an eye out for birds perched on the eggs and very closely attached to their nest.
