Here the squirrel is carrying a pinecomb that he gets seeds from the openings to eat. Sometimes he may find an accorn for food too.

Reproduction

American red squirrels are spontaneous ovulators.[17][18] Females enter estrus for only one day, but venture from their territory prior to ovulation, and these exploratory forays may serve to advertise their upcoming estrus. On the day of estrus, females are chased by several males in an extended mating chase. Males compete with one another for the opportunity to mate with the estrous female. Estrous females will mate with 4 to 16 males. Gestation has been reported to range from 31 to 35 days.[19] Females can breed for the first time at one year of age, but some females delay breeding until two years of age or older. Most females produce one litter per year, but in some years reproduction is skipped, while in other years some females breed twice. Litter sizes typically range from one to five, but most litters contain three or four offspring. Offspring are pink and hairless at birth and weigh about 10 g. Offspring grow at approximately 1.8 g/day while nursing, and reach adult body size at 125 days. They first emerge from their natal nests at around 42 days, but continue to nurse until approximately 70 days.

Nests are most commonly constructed of grass in the branches of trees. Nests are also excavated from witches’ broom—abnormally dense vegetative growth resulting from a rust disease—or cavities in the trunks of spruce, poplar, and walnut trees. Kluane red squirrels rarely nest below ground. Each individual squirrel has several nests within its territory, and females with young move them between nests. Some behavior has been reported within human dwellings using insulation as nesting fodder.

A three-year study of a population of red squirrels in southwest Yukon reported female red squirrels showed high levels of multiple-male mating and would even mate with males with similar genetic relatedness. While males mating with multiple females is quite common in the animal kingdom, females that mate with multiple males is rarer. When female red squirrels chose a mate, genetic relatedness did not play a factor. The relatedness of parents had no effect on the neonatal mass and growth rate of their offspring, nor did it affect the survival rate of offspring to one year of age.

Hello Trevor,
This is definitely what I call a keeper. Showing an animal in it's habitat doing what it naturally does is always a pleasure to view.
You have done a fine job of presenting this cute little Red Squirrel with a pinecone in it's mouth. Focus is great and colors are well saturated yet natural. Nice work!!
Ron
