Bears, Shots After Hours, and Worms - UPDATE October 3, 2019

Checking around, mothers with cubs are still active and alive—Samantha, Donna, Oliana, Braveheart, Ursula, and several non-clan mothers. Pregnant mothers have drifted away, except RC who is still being seen. Braveheart - 2016Braveheart - 2016Mature males have mostly drifted away. Shots after hours, as late as 11 PM, worry us, but the baits we knew of earlier have all been pulled. We’ll be looking hard next year to see who shows up with cubs and all.

Donna - 2019Donna - 2019I’m learning more about intestinal roundworms, including what a veterinarian says that the raccoon roundworm Baylisascaris procyonis passed its eggs through the uterus to infect pups born to infected dogs. Although it is said that the bear roundworm Baylisascaris transfuga that lives off ingested material in bears dies and is defecated as the bears approach hibernation in September and October, no one knows what triggers the purging. The worms in the scats in this community were from bears that were still eating. One biologist says that a change of diet to roughage like coarse grass can purge tapeworms and maybe roundworms. June Bear and her cubs showed us that they eat a lot of coarse alder leaves at this time of year. Some of the bears that we have seen in the last few days are eating coarse fall grass now. Many unknowns.

Thank you for all you do.
