Recent Ringed Kingfisher Sightings in
the Texas Hill Country
TexBird Archives has over 700 records from 1998 through 11/2005 of
Ringed Kingfisher sightings in Texas.
Of these, about 140 fall outside south Texas, the Rio Grande, and the
127 of these records have location descriptions good enough to spot the
distribution.(located to better than a half-mile)

Those being the most popular tubing stretches, perhaps either the
birders do not like tubers and do not bird there, or the kingfishers do
not like tubers.
Nearly half the records are from Austin birders logging the birds
around their town.

Abundance throughout the Year

Abundance throughout the decade
This chart clearly shows the birds have
doubled or tripled their
numbers in less than a decade in the hill country.
When the sighting dates are color coded, the pattern seems
random. So the range extension cannot be seen in the narrow
1998-2005 data set.
The symmetrical shape of the monthly abundance curve (no peak just
after nesting season), suggests the lack
of breeding records for the hill country reflects reality.
Perhaps a few breed but not enough to show up in the abundance numbers.
Range extension north and northeast during this decade has been
much slower than the increase in abundance of the birds within the hill
Abundance within the hill country has at least doubled this decade.
Thanks to TexBirds for archiving all
those postings and for allowing the archives to be queried.
Thanks to the birders of the state for
posting their sightings to TexBirds.
