Thursday September 4, 2025, and here’s your Thursday tour. We’re moving right along with fall baby season, late season birds, and illness/injuries. There’s a “sweet spot” regarding how long animals, especially orphans, stay in wildlife rehab. Too little time can set them up for failure, and too much time can actually cause some animals to regress. This time of year, changing weather is a big consideration as we prepare to transition into fall, and from fall to winter. Animals take many cues and instincts from their environment. Light and dark cycles, or the change between day and night, helps animals know when it’s time to mate, and when season change is coming. How do they know it’s coming? The same way you know it’s coming, except their bodies rely on this info for survival. The days become cooler, the daylight hours become fewer, and for some animals, food sources start to change or become scarce. For many birds, like our hummingbirds, this signals them that it’s time to migrate. Flowers become less abundant, days are shorter and cooler. For other animals, their bodies naturally start to respond to the environmental changes to prepare for the season ahead. What does that mean for wildlife? As days become cooler and daylight hours shorten, animals go through hormonal changes that cause them develop their winter coat. If you’ve ever called me in fall and told me about the animals you’ve illegally kept all summer, you have likely heard me tell you many things, including the fact that the animal is not equipped for survival because their time in the house has prevented them from developing their winter coat. When animals are kept inside your house, not only are they living your life of high crime, but they’re also being kept in artificial light and controlled temperature. It is crucial that animals in rehab are exposed to natural light (that’s the sun, folks), light and dark cycles, and changes in temperature. Their bodies know what to do to prepare them for the winter ahead, and it starts now as these cooler temps and shorter days begin. Many animals also start to develop fat reserves and start caching food (watch the squirrels in your yard begin to bury things!). Ideally, most animals in rehab are able to be released in fall with plenty of time to naturally acclimate for winter. In the instances where they’ve not had this time to acclimate, some may need to be over-wintered. Though we may not like these shorter days and the cooler weather moving in, these subtle changes are crucial for our wildlife surviving the winter ahead.
