There was a Robin's nest in a low tree by my house with 5.

A.The eggshell color comes from the mother robin's blood.Hemoglobin from broken blood cells is transformed intobile pigments, which are carried by the robin's blood to where the eggshell forms.She doesn't need anything special in her diet to have colored eggs.

A.How sad.Eggs are doomed if the female is killed.The male does not know how to brood eggs.

A.A completed nest is necessary for the robin to have a place to lay her eggs.She usually starts within a day or two, but there are a few things that can affect the timing.She may not have the energy if the weather is bad and she spends a lot of time looking for food.She might be delaying because she won't be able to produce the heat she needs.Even though the nest is built, the female may not be ready for egg formation in a very late spring.

A.Most clutches have 3 or 4 eggs.When a robin lays an egg in another bird's nest, there are usually 5.There are sometimes only 2 eggs in the second and third phases of a season.

They get a lot of their calories from eating worms.They find their worms by sight, so there needs to be a little light for them to hunt, but the worms hide soon after sunrise.Robins lay their eggs first thing in the morning.

There are two birds in our yard.An egg was found on the ground in a different part of the yard.The four eggs were gone when I checked the nest.I think blue jays may have taken the nest.

A.The eggs are doomed if the female is killed.The male does not know how to brood eggs.If it was the male who died, the female may give the nest up for lost because the chances of bringing off more than one or two nestlings is very small.The female starts focusing on a new bunch of eggs after the young fledge, so the father is essential for the lessons on surviving.Cats outdoors cause heartbreaking individual losses and are a serious ecological problem.I am very sorry.Please write to let us know if one of the parents attends the nest and what happens, as this is the best way for scientists to learn about the differences between the two parents.

Blue jays, crows, snakes, and squirrels are some of the main predatory animals of robin eggs.A lot of bird eggs and nestlings are eaten by deer.Since you found one egg in the yard, a snake most certainly wasn't the culprit.I think it is not a squirrel, because they stay up in branches and rarely drop their eggs.It's hard to know which bird raided your nest because they are both egg and nestling eaters.jays are good at warning about other dangers if they stay away from their nest.It is heartbreaking to lose the eggs or nestlings in a nest.The worst problem with crows and jays is that they are very smart.If you are looking at the nest in your yard, make sure you don't see crows or jays.They might start looking for you to lead them to their next supper if they figure out that you are watching the nest.

A.Leaving an egg be is the best thing to do with it.There is a chance that there isn't a baby in there, but I know you're worried about that.This may be an egg that wasn't fertilized.After the other babies are a day or two old, the parents get rid of unhatched eggs just in case one of the growing babies accidentally crush it.Eggs that are rotten are not fun.

There is a chance that there was a baby inside the egg.The predator may have dropped the egg in a panic as the angry parents dive-bombed it.The baby inside may have been badly shaken when it was dropped and the egg looks fine on the outside.If that is the case, the baby inside may already be dead or soon die, and if it does survive to hatch, there is a strong chance that it will be badly deformed, making its short life unendurably painful.

The chance of a human successfully raising a baby from a hatchling is very remote, even if the egg is healthy.Robin eggs need high humidity, gentle daily turning, and level heat.To do it properly, you would need a high-quality incubator.Humans can't feed their babies worms and insects for the first three or four days after birth.Newly hatched robins are weak and helpless, and their parents have the right instincts for taking care of them.Our human hands are clumsy, and we have too many other concerns in our daily lives to devote every waking moment to a baby bird.

People underestimate the amount of food baby robins need, giving them too much in single feedings and not enough over an entire day.The parents return to the nest every few minutes from sunrise to sunset as they search for food.Is it possible to do this consistently for several weeks?It is difficult to make a baby bird diet balanced.Young worms, insects, spiders, and some fruits are fed by the ravens.The baby needs a few rays of sun each day to get the required amount of D3 in their body.It is difficult to make a precise balance of calories and vitamins and minerals in the indoors.

It is against state and federal laws to raise wild baby birds in the US.Babies can be hurt by death at the hands of people who aren't feeding them the right diet.It's better to allow the egg to cool.The baby will stop developing within the egg if it is still alive.

There are seven eggs in the nest, but suddenly the birds are gone.The mother has not been seen in 4 days.

A.It is against state and federal laws to keep wild birds.When something tells the robins they will have a poor chance of success, they abandon their eggs.Humans are not likely to have greater success.I know how sad it is to see these beautiful eggs and how tempting it would be to save the tiny babies inside.It is heartbreaking to watch the babies start out healthy, with their egg sac to provide some nutrition for a few days, and then wither and die at our hands.

The seven eggs are too many for one bird to have laid.There must have been more than one bird laying her eggs.It may have been the reason it was abandoned.Robins are called determinate layers by ornithologists.After a female robin lays four or five eggs, her body stops producing more until she's raised these.

Before I knew the plant was higher than I could see, I watered it with warm water and poured it over at least one of the eggs.The mother is not moving.There is a chance that I have harmed the eggs.

A.Anything that is outside has to be waterproof.The eggs that got wet should be fine if they weren't sitting in water for more than a few minutes.

I was able to water around the edges because the nest is in the middle of the plant.I don't know if I will harm the eggs and baby birds when they hatch.

A.It is okay to water around the edge of the plant, but don't water after the babies are close to fledging, and give the mother time to fly off each time.
