When discussing squirrels, it’s important to note that they belong to the rodent family and often live in social groups, which means they don’t typically build individual nests. However, female squirrels have a unique nesting behavior during their pregnancy. They construct a nest known as a “drey” to accommodate their growing family. This nesting behavior is most commonly observed at the beginning of the summer season when female squirrels are more likely to enter their estrus cycle and have a higher chance of becoming pregnant. The construction of these nests is driven by their specific needs and requirements to provide a safe and comfortable space for their young.
