Good thoughts, Pete, thanks. Thanks also for mentioning the 7 simple actions link, it is a good one! Jane Orbuch made some posters in a larger format, and we usually display them at birding events. On the topic of planting natives = more caterpillars = more baby bird food, Doug Tallamy’s Homegrown National Park park is awesome: https://homegrownnationalpark.org/.
By the way, this coming Saturday will be a small Migration event at Natural Bridges. If anyone is interested in helping in some way, please contact me.

That is why when I look at data on ebird to try to tease out trends, I try to limit the data to the last 10 years. If nothing else, we know that land use and climate patterns have changed significantly in the last 50 years. Not to mention the estimates, that we have lost some 2.9 billion birds in North America since 1970. (source: https://www.birds.cornell.edu/home/bring-birds-back)

Does that seem correct, or might that be a late migration that people have been mentioning? If late is the case, then maybe it will continue rising more steeply…?
