We outfitted squirrels with small motion sensing collars that collected data as squirrels moved through their environment.
These collars used accelerometers, magnetometers, and gyroscopes to measure different aspects of a squirrel's motion. These sensors are similar to the ones in our cell phones and smart watches that help us measure how far and fast we have traveled or flip the orientation of our screens when we turn our phone from vertical to horizontal.
Here is Diva the California ground squirrel modeling her collar for
High canopy connectivity is another way of saying 'a lot of connected branches.' Tree squirrels prefer to travel up in the trees to avoid predators on the ground. They use this interconnected branch network as a super highway to move through the forest. In order to do this they need large areas that have a lot of mature trees whose branches overlap. Research has shown that squirrels prefer to leap about 3 feet across at the maximum . Thus, an area with high connectivity would have lots of branches at this distance or less.
Along with finding Petry, Lisette found a second baby squirrel in her yard who she named Ducky. Ducky did not appear to have any obvious bone injuries and was not bleeding or crying. As Lisette approached Ducky he began to move on his own.
If you come across a baby squirrel like Ducky who does not appear to need immediate medical care the best option is leave the squirrel where you found it. Keep people and pets away from the area for a day and give the mother squirrel a chance to come back and relocate her baby. 🐿💕👼 If it is very cold outside it may be a good idea to place the baby on a blanket.
If by the end of the day the mother has not come back it may be time to bring the baby squirrel to a rehabilitation center as it will likely not survive the night outside on the ground alone.
