It’s great to hear from so many of you and your local observations. I think reports around these pivotal times of the year (like the autumnal equinox) serve to highlight slight differences in our local biomes and habitats. They may also hint at migration pathways. I’m surmising that not all habitat is equal but critters will fan-out over all the land in an attempt to eek out a living and replicate. I’m thinking of migration as a flood of wildlife across the land. When daylight hours shift to a point, it’s like raising that land and having the water “wildlife” begin forming rivulets and creeks and streams and rivers all moving along the great migration flyways. Once arrived at their winter grounds, the reverse is true where congestion leads to dissipation where the fan-out across the countryside with the most capable occupying areas of densest food availability while those less able (or more creative) move to sparse highlands and cliff faces, each according to their ability and adaptability. I think seasonal migrations contribute a lot to species diversification and evolution in general. Crazy thoughts on an early autumn evening.

There are still at least two juvenile hummingbirds at our place in Ypsilanti.

The last Hummers hanging around here left about four days ago. The last Monarch to eclose here happened about the same time. I still have a few chrysalises but they’re “duds” by now and are never going to emerge. Researchers are talking a lot about this record El Niño and the anticipated weird winter we’re going to have and have surmised many creatures have already left early. Any still around your places?
