Subject: [ia-bird] New Johnson County Big Day Record

On May 10, 2018 four intrepid birders set out to break a long-standing Big
Day record for Johnson County. Diana Pesek, James Huntington, Mark Brown
and myself started at 4:30am near Hawekeye WMA, hearing Great Horned Owl
and seeing Eastern Screech-Owl and Barred. We quickly ticked off American
Woodcock and Sandhill Crane near Round Pond. Eleven species of waterfowl
at Swan Lake plus several species of shorebirds at Swan Lake and the end of
James Avenue were a nice surprise. Before heading to Hickory Hill Park we
had ticked over 100 species in and around Hawkeye WMA. Things were getting
off to a great start!

Trips to Hickory Hill, the Coralville Dam and Squire Point Trail were
fairly slow, but we picked up a few new birds here and there. When we were
around 20 species away from the previous record (136) there might have been
a little doubt among group members that we would not so much as tie. I
said jokingly, "I didn't sign up for this to not beat the record". A trip
to Hanging Rock ended up pushing us to the point where we thought we had
it. Visits to Twin View Heights and the South Arm of Lake Macbride pushed
us over, tying with Wilson's Phalarope and beating with Greater
Yellowlegs. James instilled in the group that we could not beat the record
with an introduced species (e.g. Eurasian Collared-Dove, Mute Swan, etc.).

We had an absolute blast together and enjoyed the company of fellow birding
pals. The weather could not have cooperated more! It didn't quite get
over 80 degrees in the afternoon and there was little to no wind all day.
We ended up with a final tally of *143 species*. We had 23 countable
species of warblers (a single Orange-crowned we didn't get at least three
people from the group on), 11 species of shorebirds and 12 species of
sparrows. We missed considerably better shorebird habitat and diversity by
about 2 days. We certainly didn't have a banner sparrow day!
