Does a mother beaver have different mate every year?

No, mother beavers generally do not have a different mate every year.

Beavers are known for forming monogamous pair bonds that can last for many years. They establish territories and build their lodges together, and both parents contribute to raising their kits.

While there are instances where pairs may break up, it's usually due to factors like death or the inability to successfully raise young.

Here's a breakdown of typical beaver behavior:

* Pair Bond Formation: Young beavers typically leave their family groups and find a mate to form a pair bond.

* Territory & Lodge: Once paired, they establish a territory and build a lodge.

* Kit Raising: Both parents work together to raise their kits, feeding, grooming, and teaching them important survival skills.

* Long-Term Relationship: Their bond can last for many years, often until one partner dies.

It's important to remember that there are exceptions to every rule. While the typical scenario is monogamy, there may be rare cases where a pair breaks up or a new mate is found if the original mate dies. However, this is not the norm.
