I pulled into my yard one day to see no less than 30 deer milling around. I was shocked! The more I could see the more I saw. I thought it was a party, there were so much deer there. Prior to this, the most I had seen were five. So six times the max, until then.
I expected to see a semi truck offloading them, or a UFO lowering them down in a ray of gravity, or a keg and a boombox and dancing and carousing. I was stunned. AND, I've never seen more than two or three since. No idea what happened...
Tangent for wild wildlife sightings: I pulled in about six years ago and saw over 150 geese milling around in the yard. They looked at me, shrugged, and kept doing what geese do (eating and leaving the most enormous poop for a bird that size). The noise was 'noticeable'. HONK HONK HONK They did that for the next couple of years, and apparently we lost a gold star because they stopped showing up. We did have about 20 this year, about 2 weeks ago, but they haven't returned en mass. That group was obviously an inspection team sent to see if we had improved enough to be added to the list of 'Must Poop At' places, and we failed to measure up, which is odd as I've got trillions of small crickets hopping all over the yard. I thought they would be tasty, and they would come and eat them, but apparently crickets isn't what does it to get that gold star back. I'd trade 150 pounds of poop for dramatically less crickets.
And cicadas? I found one, dead from embarrassment no doubt. They just never were a thing here, even though we have had lots of them during advertised waves in the past. Weird...
And the falcons ate all of our wild, and well fed rabbits.
