Parental care for crows
If we look around the world, we can see that many other creatures share the earth with humans. Like there are so many animals, birds, sea creatures, and other things that give us a feeling of nature. Every being is spending life with different patterns, but one thing is mutual between all beings. So, one common element is “Parental care.” If we specifically talk about the bird, then they also have the spirit of parental care. In this piece of writing, we are specially going to focus on parental responsibility for crows.
What is Parental care for crows?
“The most exciting part of parenting is watching the personality of your little one.”
It is common practice for every living creature to raise their kids with extra care, and so is the situation in case of crows. In parental responsibility, the father and mother of crows ensure the development and survival of their offspring. The father and mother invest their time profoundly, and it considers the mutual effort. A renowned columnist, Cornell Plantations, spent most of his time observing crows’ habits and parenting. He started his research in the mid of 1960 and found the following things:
- And parenting care
Most of the offspring never return to their nest soon after they know the survival tactics. The family does not come back home to meet their parents, and then mother and father usually live with their younger ones. Some of the offspring stay with their parents for up to 5-6 years. The bird spends at least one year with the parents; meanwhile, he learns the skills to survive.
Types of parental care for crows
The crow’s parenting system is almost similar to humans, and every pair has a different pattern to act. According to their set standard, there are the following types through which they do parental care.
Biparental care: It is one of the most common types of parenting where mothers and fathers both try to fulfill their responsibilities equally. Apart from the crows, it happened in the 85% species of birds.
Maternal vs. paternal care: In this parenting, the male takes the responsibility to provide the food and female acts as a caretaker. In this type, a female is responsible for keeping the offspring warm, protected, and away from hot and cold weather.
Mono paternal care: Male only parenting happens in only one percent of the crows, whereas female only care happens in 8%.
Factors affecting parental care
As we discussed earlier that some offspring do not leave home until they reach the age of two. No crow can go for breeding at the age of two, but there are still the following factors affecting parental care:
The unbalanced ratio of males and females birds is one of the big problems in parenting. Female crows have more available mates compare to the male ones. According to research, 15% of the female crows leave their nest when the offspring is 14 days.
A female bird determines the sex of offspring
A female bird can determine the sex of a child long before hatching. In birds, the female’s egg determines the sex of the child instead of male sperm. So, the female bird determines the sex right after egg production. If the size of the egg is small, then there are few chances of survival, bigger big has more survival chances.
Timing and temperature
The timing and temperature of the offspring birth play a significant role in parental care for crows. Usually, crows go for the mating in the spring season, and if the spring arrives early than the average time, then it is not suitable for offspring. Parents go for breeding, which neglects the parenting of the child.
Benefits of parental care for crows
In most cases, mothers give more time and care to their offspring instead of their father. If both of the crows provide the same amount of time to brood, it can enhance their reproductive success. So, apart from this, there are the following benefits of parental care:
- It increases the chances of the offspring’s survival in the time when he needs his parents most. In short, the time right after birth is most vulnerable, which demands parental care for survival.
- It increases the reproduction capacity of the offspring, and he can spend life even after separating from the parents.
- Parents help the offspring to build knowledge related to their generation.
- Parenting protects the offspring from threats by creating different warning calls.
Crows have warning calls for following threats:
- The cats
- For the hawks
- And one for the humans.
