Yes, true worldwide, but I'm thinking of the local ones. And specifically my yard.
I keep a mostly organic yard (OK, I spray individual poison ivy plants). But I do things to help the birds and bees and other stuff thrive. Half my backyard is left semi-wild. Lots of small trees for bird-nesting. I have black oil sunflower seed in one feeder for most songbirds, 2 thistle seed feeders for the purple and gold finches, and 2 nectar feeders for the hummingbirds.
I have 5'x3'pond for frogs. With plants and debris at the bottom to support aquatic insects. I have butterfly bushes, pollinator plants, and plants that insect larvae can develop on.
I used to see some possums and raccoons at night. I used to hear thousands of Spring Peeper frogs in the swamp across the street in the Spring.
But that has been changing. I noticed a few years ago that the Swamp was quiet; no Spring Peepers calling in the thousands. I used to see deer in my front yard and the neighbors in snow prints and visually. I used to see snow prints of other various critters.
When I moved here 37 years ago, there were no cardinals, finches, etc. But when I set up feeders, I got up to 6 pairs of cardinals, a bunch of purple finches, a dozen goldfinches, and various smaller birds (titmice, wrens, woodpeckers, etc). Sometimes, the sunflower seed feeder was mobbed by starlings (I did tend to chase them away as they would just empty the feeder in a few hours, leaving nothing for the other birds and the stuff is somewhat expensive). I haven't seen it mobbed in a few years.
I think we are in trouble. If my generally organic semi-wild yard can't support cardinals, finches, and other small birds with good food, something is going very wrong. If there are no frogs in the pond, something is very wrong. If the deer (those damned landscape-eaters) are becoming more rarely seen, something is very wrong.
My hummingbirds haven't come back this year. I haven't seen a single butterfly. I haven't seen a possum on the deck at night. I haven't seen many bees (Honey or Bumble) and it has been warm enough for a month. I haven't seen any hornets (not that I love them). But still, that is not a good sign.
Something is going bad, and I think we are causing all this. As Pogo said "We have met the enemy and it is us".
