Wow. Isn't it great when you take a careful look at the data.

Vineeta and David,
I was surprised you said your numbers have dropped because I've been
seeing
the W.T. Sparrows nearly every day since they arrived in October. And it's
been the same the last winter and several before that. BUT I decided to do
some checking and not just go by impressions. I've been counting birds for
Cornel's "Project Feeder Watch" for many years. They keep track of all the
entries so I went back to 2015 when I moved to my new house. The counting
season is from mid November to mid April. You count two days with five
days
in between. Here's what I found. Below I wrote the average group size of
the
2-day count and the highest number of the birds seen during any of the
count
days. I hope the chart comes out looking okay.
2015 - 2016 Average group size 4.5 and highest 9
2016 - 2017 average 4.3 and highest 7
2017 - 2018 average 3.3 and highest 5
2018 - 2019 (so far) 2.7 and highest 4
So they are declining here!!

I've noticed a huge drop in numbers in my garden. And it makes me very sad.

Have folks in VA noticed a drop in numbers from previous years? Accordinghttps://ebird.org/science/status-and-trends/whtspa/trend-map-non-breeding,
to ebird,
the trend doesn't look good. I've seen almost zero on trips I've led.in
Ironically, I had one bird in my yard this am. I also had a single bird
Nov. All the above is highly unusual.
