I live in the city but I get birds that are usually only found in the forest because they like to forage in the fallen leaves! It does make a difference.
When I was a kid, I heard that leaving cut grass on the ground was better for your lawn. Surprisingly, this was enough to convince my dad that I didn't need to bag the clippings when mowing.
If you have a few trees you can just mow over the leaves right on the lawn which breaks them up enough for your fall fertilizer if you don't have a use for them. The last few years I've been using mine to compost in place my gardens. Haven't had to bag since
