Las marmotas, también conocidas como marmotas, son roedores no monógamos que se aparean cada primavera para producir aproximadamente seis cachorros. Aproximadamente a los dos años, las marmotas comienzan a aparearse. Los machos establecen territorios y luego buscan marmotas hembras para comenzar su práctica de apareamiento cada primavera.
Los machos se aparean con numerosas hembras para producir tantos cachorros como sea posible. La razón por la que los machos son tan firmes sobre la reproducción es que las hembras tienen capacidades reproductivas mínimas. Las marmotas hembras pueden aparearse solo una vez al año, durante su período de fertilidad primaveral.
Las marmotas hembras dan a luz a sus crías dentro de las guaridas. Las guaridas subterráneas son grandes y a menudo están hechas de múltiples «habitaciones», lo que las hace cómodas para camadas grandes. Después de dar a luz a los cachorros, la madre cuida de sus cachorros durante siete semanas antes de dejarlos salir de la guarida de forma independiente.
La marmota solitaria busca un compañero realizando técnicas de cortejo. Los machos encontraron territorio y luego se aparearon con las hembras dentro de ese territorio. Sin embargo, otras marmotas macho pueden invadir el territorio y apoderarse de sus tierras socializando con las marmotas hembras antes de que el macho territorial tenga la oportunidad.
Una vez que las hembras están listas, los machos pasan unos días conociéndolas, y eventualmente, se aparean en algún momento entre principios de marzo y finales de abril, dependiendo de cuánto dure la hibernación.
¿Las marmotas tienen una llamada de apareamiento?
Las marmotas no tienen una llamada general de apareamiento. Sin embargo, silbarán a otras marmotas para indicar que están en el área. En lugar de hacer sonar una llamada de apareamiento, las marmotas machos visitarán las guaridas de sus parejas potenciales para ver si están disponibles.
¿A qué edad comienzan las marmotas a buscar pareja?
Aproximadamente a los dos años, las marmotas comenzarán a aparearse. En este momento, la marmota debe haber establecido un territorio para sí misma donde hay solteras o solteros elegibles.
Las marmotas también pueden comenzar a aparearse al año si maduran lo suficientemente rápido o encuentran una pareja elegible (o parejas) antes.
¿Las marmotas se aparean de por vida? ¿Son monógamos?
Las marmotas son criaturas solitarias y antisociales, y generalmente no les gusta compartir sus madrigueras con ninguno de sus amigos o familiares.
Llevan una vida solitaria y no necesitan un compañero romántico como compañero de vida: son capaces de valerse por sí mismos, encontrar comida, crear su madriguera y proteger su hogar, todo por sí mismos. La única situación en la que realmente necesitan una pareja es para reproducirse.
Las marmotas machos suelen buscar múltiples parejas femeninas. Al buscar múltiples parejas, el rendimiento de los cachorros de marmota es mayor.
Aunque los machos buscan múltiples parejas, están atentos a cada pareja. Durante el invierno, los machos saldrán de sus madrigueras antes de que termine la temporada de hibernación para controlar a sus parejas y garantizar su seguridad. En algunos casos, protegerán a los enemigos para proteger a sus compañeros y cachorros.
When Is Groundhog Mating Season?
Groundhog mating season is in springtime, between March and April. The roughly thirty-day gestation period that follows means the pups are eventually born in summertime.
It takes groundhogs roughly seven weeks to mature before the pups set out on their own in fall, where they build their dens and prepare for winter on their own.
How Do Groundhogs Mate?
Groundhogs are polygamous mammals whose brief courtship is a critical part of their breeding process. Male groundhogs can mate with multiple females during their fertility season. However, they are highly competitive and must win the female over before beginning the mating practice.
Mating season precedes hibernation. Therefore, male groundhogs will visit the underground burrows of their potential partners to socialize. They pull their partner from torpor to romanticize them.
Introducing themselves and making the females comfortable increases their chances of becoming the chosen partner. (Makes sense, right?)
Male groundhogs who have domain over several female dens will wake early from hibernation to defend their territory. Although the relationships of groundhogs are polygamous, males still defend the females in their territory as their partners.
Do Groundhogs Make Noise When Mating?
Groundhogs make several noises as they mate. Low and high-pitch whistling sounds are the most common noise groundhogs make. Groundhogs make this noise when mating and while feeling threatened.
Groundhogs mate only once per year because females are only fertile once per year during springtime, which is why male groundhogs tend to mate with as many females as possible.
Mating with multiple females is assurance for the male that reproduction will be successful. Multiple partners may also influence the potential of larger pup yields.
While some woodchucks might produce only one or two pups, it can be possible to mate with a groundhog that yields eight. The uneven numbers are, therefore, balanced out.
Do Groundhogs Have Babies Multiple Times Per Year?
Female groundhogs can only mate one time per year during their springtime fertility period. Although they can only have babies once per year, groundhogs have large litters of roughly six pups.
Large litter production means that the groundhog has no problem maintaining its population, despite being prey to many larger predators like foxes, bobcats, coyotes, hawks, and domestic dogs.
How Long Are Groundhogs Pregnant?
The female groundhog’s gestation period lasts between thirty to thirty-three days. The number of babies that the groundhog gives birth to depends on her size, health, and genetics.
The average number of a groundhog’s litter size is five to six groundhogs. The number of groundhog babies females birth can range between one and nine.
The female lays low in her burrow (called a sette) while the babies are growing.
When Do Groundhogs Have Babies?
Groundhogs have babies in the summertime, roughly thirty to thirty-six days after their springtime mating session.
If groundhogs mate too late in the mating season, their babies will be born too late and, therefore, will be unprepared for winter.
Depending on when the mating happened and how long the gestation period took, the babies are typically born between May and June.There are between 2-6 baby groundhogs per litter, which is a lot for the new groundhog mom to look after!
Groundhogs are born without hair and can’t see yet, so they are very helpless. The mother takes care of them and nurtures them until they’re strong enough to head out in the wild and start exploring the land around them.
How Do Groundhogs Give Birth?
Groundhogs are mammals who give birth to their babies by live birthing. They birth their pups one at a time, having a momentary break between each pup. The mother births her pups in their burrow, where they remain for the next few weeks.
The groundhog mother births her pups alone. When birthed, the pups are entirely blind and deaf. They remain in their burrows with their mother for roughly seven weeks. Female groundhogs care for their pups and do not leave their side during these seven weeks.
Do Groundhogs Lay Eggs?
Groundhogs do not lay eggs because they are mammals and only two mammals lay eggs, the platypus and echidna. Many animals, aside from birds and fish, lay eggs. However, the groundhog is not one of them.
The groundhog is a warm-blooded rodent that will give live birth to its pups in a burrow during the summertime only a month after conception.
There are roughly six groundhog babies in a litter. This average can vary depending on the size and genetics of the groundhog. Typically, larger females can bear larger pups. Furthermore, genetics may also influence larger litters.
What Are Groundhog Babies Called?
Groundhog babies, newborn and maturing, are called pups. Young groundhogs can also be referred to as kits. Chucklings is a common term for folks who refer to groundhogs as woodchucks.
Do Groundhog Pups Make Any Sound?
Baby groundhogs tend to make a few sounds, including squeaking, whining, and crying, but also teeth chattering. The most common sound that groundhog pups make is a gentle squeaking noise. A squeaking noise indicates their needs.
Since squeaking noises are quiet, groundhog pups may also increase their tone. Loud crying expresses an immediate need. Groundhog pups might use this sound if their mother leaves the den or they accidentally wander away from the litter. Wandering from the litter can lead to groundhog pups becoming cold, fearful, and lonely.
In the below video, a baby groundhog is making a teeth-chattering sound as a kind of warning signal. It’s really quite cute.
What Do Groundhog Babies Look Like?
Groundhog babies are less than four inches long and weigh just under an ounce, or 25 grams when born. They are as small as squirrels.
Baby groundhogs have a similar appearance to squirrels when they are born because of their slim size. As the groundhog matures, they gain weight. As adults, they will be quite large, and can weigh as much as 13 lbs!
Initially, groundhog pups are blind, with ears folded inward. Baby groundhogs do not emerge from the burrow before their eyes open and ears adjust. Therefore, it is uncommon for humans to see groundhogs in their first few weeks.
How Big Are Baby Groundhogs at Different Ages?
At birth, the baby groundhog weighs roughly 1 oz or a bit less. Newborn groundhogs are slightly larger than 3 inches and grow relatively quickly. By seven weeks, after the mother has weaned her pups from her milk, the pups will have increased in size significantly.
In general, male groundhogs are larger than female groundhogs. The male groundhog’s increased size includes facial structure, weight, and body frame.
How Do Groundhogs Take Care of Their Young?
Male groundhogs are generally uninvolved when it comes to taking care of their young. The only time male groundhogs are actively engaged in caring for their young is during the first seven weeks of their lives. During this time, they roam their territory to ward off predators.
Female groundhogs take care of their young very closely during the first few weeks of their lives. The mothers nurse their young to provide them with the food they need until they are roughly forty-five days old.
After weaning their young, mothers provide their young with guidance and encourage them to dig their burrows.
What Do Groundhog Babies Eat?
Groundhog pups rely on their mother’s milk for the first few months of their lives. After roughly forty to forty-five days, mothers wean the pup’s from her milk and introduce them to traditional foraging tactics.
¿Cuánto tiempo permanecen los bebés de la marmota con su madre?
Las marmotas tienden a permanecer con sus madres durante aproximadamente seis a siete semanas. Debido a que son ciegos al nacer, permanecen con su madre en función de cuánto tiempo permanecen ciegos. En general, las madres marmotas cuidan a sus cachorros el doble de su período de gestación.
¿Las madres marmotas alguna vez dejan a los bebés?
Durante las primeras semanas de sus vidas, las madres marmotas no dejan a sus bebés. Después de siete semanas, cuando sus cachorros adquieren su visión y audición, las madres comienzan a sacar a sus cachorros de su guarida y les permiten explorar el área circundante.
Las madres supervisan a sus cachorros mientras exploran mientras obtienen comida para sí mismas al mismo tiempo.
¿Cuándo comienzan a salir las marmotas juveniles?
Las marmotas salen de sus madrigueras después de seis o siete semanas. A las siete semanas, las marmotas han desarrollado su vista y oído. Los cachorros también han destetado de la leche materna y están comenzando a aprender técnicas de alimentación.
A medida que los cachorros comienzan a explorar el territorio circundante, permanecen bajo la supervisión de sus madres. Si se enfrentan a peligros, su madre silbará y todos los cachorros se apresurarán a regresar a la guarida por seguridad.
Aproximadamente a los dos meses de edad, las marmotas dejarán permanentemente a sus madres y establecerán sus propias madrigueras. Al principio, su guarida puede estar dentro de las líneas territoriales de su madre. A medida que maduran, la marmota inevitablemente comenzará a aventurarse más hasta que finalmente estén solas.
Encontrar su territorio es especialmente importante para las marmotas macho, que deben tener su propia tierra, o capturar la tierra de otro macho para comenzar el proceso de apareamiento en su segundo invierno.
¿Cómo saber si una marmota tiene bebés?
Las marmotas con bebés son más defensivas de su territorio. Los machos a menudo combaten a los depredadores que se acercan y otros machos que intentan invadir el área durante la temporada de apareamiento. Las hembras también están en alerta máxima después de dar a luz a los cachorros.
Las hembras son muy cariñosas con sus cachorros, y observan a sus crías de cerca.
¿Qué hacer si encuentras una marmota bebé?
No mueva ni toque a las marmotas bebés si las encuentra solas. Llame a un centro de vida silvestre si encuentra una marmota bebé abandonada para que puedan moverla y cuidarla.
Es casi imposible que las marmotas bebés sobrevivan sin sus madres debido a su incapacidad para usar la mayoría de sus sentidos al nacer. Los expertos en vida silvestre saben cómo transportar, cuidar y rehabilitar a las marmotas bebés.
