***Discussion via Bullet Points:
- 333 species have been reported to eBird all-time for Delaware County. Five new species were added to the Delaware County eBird list since 2017’s Black-headed Gull. These were Ross's Goose (Media), American White Pelican (Haverford College), American Golden-Plover (Delaware River), Hudsonian Godwit (Deleware River), and Gull-billed Tern (Deleware River).
- 226 species were listed on eBird for Delaware County in 2019, 5 less than in 2017 and 7 less than in 2018. The 226 species seen in 2019 was due in large part to two birders who were very active in the county in 2019.
- A new total species high count was set for 3 months out of twelve: February, August and December 2019 shown in red in the above table.
- 100+ species have now been reported in nine out of twelve calendar months at least once, leaving only the winter months December thru February outstanding. December came oh so close with 99 species recorded.
- 150+ species is a tough number to reach in any month. Previously, only three months have achieved that lofty number: April, May, and September.
- 49 species have been reported for Delaware County for every one of the eBird bar chart weeks in a year.

The top 100 birders in Delaware County submitted 226 species and submitted 4451 (a decrease of 49%) separate checklists. It shows a substantial lack of reporting in 2019. Why is that? I have not a clue. Perhaps the Delco birders are just getting too old to bird. I know I'm feeling the effects of too many years.
