Otter Tales Part II: More Otter Tales. (See May 4th blog for Part I)
Along the lakeshore, the Nodding Beggarticks (Bidens cernua) are about to bloom. The rushes and grasses above the waterline had been mowed in early summer and then were kept short by high water. Now their lush carpet of greenery, up to 35 feet from the water’s edge, reveals the outline of the summer’s high water. The inundation was no doubt caused by a downstream beaver dam and lasted most of the summer. That got me thinking about beavers. And otters. And the unhappy threesome I had fecklessly instigated (see my blogpost from May 4, 2023). How are those three characters who I encountered in early spring? When would mama otter have given birth? How big are the otter pups now?
Google and Wikipedia led to some more questions. How long do otters gestate? One quick answer said 58 days. Another source claimed 12 ½ months! What the hay?!
After thrashing through some incompetent-sounding websites, I found enough info to figure out the story. Although technically, gestation takes only two months, otters have the ability to delay implantation of the embryo into the uterine lining. Crazy! That implantation triggers the embryonic cells to resume dividing. This incredible reproductive strategy enables the pups to come into the world at an advantageous time (maybe after putting a down payment on a house in a cute cul-de-sac?). Apparently, and I know nothing more as yet, a lot of species do this. You learn something new every day!
SO, the pups might not have been born yet, and might not be born until April! Over a year after the dating/mating scene I (blush) witnessed. Nobody has reported seeing otters since that great date, but they (or their look-alikes) were seen yesterday morning! No babies, though!
What surprises do the water and the forest have in store for me next? Hmmm…it kinda feels like bear weather…
