California Condors in Grand Canyon

The California Condor is one of the most endangered species on earth. Whilst attending a wedding in Grand Canyon last month, we had the opportunity to search out some of these unique birds.

We saw our first condor soaring below us in the canyon while we were hiking the South Kaibab trail, but it was a distant look. We had closer views of three birds at the Navajo Bridge in Lee's Ferry, Arizona.

California Condor H9

Condor H9 is a nine-year-old female that was raised in captivity in Portland, Oregon and released into the Grand Canyon in 2011.

California Condor P5

Condor P5 is a three-year-old male that was hatched in the Los Angeles Zoo and released into Grand Canyon in 2015.

California Condor P6

Perhaps the most interesting specimen that we saw was Condor P6, a three-year-old bird of unknown sex that was hatched in the wild.

The conservation of California Condors reached its most critical moment in 1987 when the entire remaining population of 22 birds was taken into captivity. A reintroduction program was commenced and the first captive-bred birds were released in California in 1991. Condor releases in Grand Canyon began in 1996 and continue to this day. At last count, there were 276 California Condors known to exist in the wild.

The Heart of Texas

Mississippi Kite

We were recently in Abilene, Texas for a family wedding so of course we decided to squeeze in some birdwatching during our visit. We flew into San Antonio and spent a few days in the "Hill Country" before heading deep into the heart of Texas for the remainder of the trip.

Curve-billed Thrasher

Texas is fantastic for birds, but trying to locate them in the heat of July when breeding activity is largely finished is not particularly easy. Spring would have been a more advantageous season, but unfortunately the engaged couple did not consider our birdwatching preferences when they selected their wedding date. The nerve!

Scissor-tailed Flycatcher

The two most sought-after species in the Hill Country region are Golden-cheeked Warbler and Black-capped Vireo. We were successful in finding the vireo, but could not locate the warbler despite a fairly intensive effort.

Golden-fronted Woodpecker

Ladder-backed Woodpecker

Texas has a great variety of birds, but we would have had to visit the Rio Grande Valley, coastal areas of the Gulf of Mexico, the Piney Woods region and several key locations in West Texas in addition to the Hill Country to fully appreciate the richness of bird species represented within the state. The large geographical area of Texas makes a visit to all of these areas impractical in a single short visit.

Mexican Ground Squirrel

Black-tailed Jackrabbit

In addition to birds, Texas is an interesting destination for viewing reptiles and mammals. One highlight of the trip was the opportunity to witness approximately 10 million Mexican Free-tailed Bats as they emerged from their maternity colony at dusk.

Texas is also well-known for its impressive variety of flying insects, particularly butterflies and dragonflies.

Addendum: From looking at eBird I see that this is old news and there are dozens of sightings from April.

The Glades

On our annual visits to Florida we spend much of the time in the vicinity of Tampa Bay where my parents stay for the winter. Occasionally we travel further afield. This year we explored the Everglades of southern Florida.

My arrival to Everglades National Park was highly anticipated

The term "Everglades" is somewhat confusing, because it is used differently by different sources. For example, the Everglades is sometimes used as an abbreviation for Everglades National Park. The park, however, only comprises the extreme southern portion of the much larger Everglades drainage basin. Another source of confusion may arise because the boundaries of the Everglades as a natural feature are imprecise. Unlike, say, the Grand Canyon that has an easily recognizable rim to mark its boundary, the Everglades is demarcated by hydrological conditions that are not as simple to observe and that are constantly changing. Further confusion may arise from the fact that significant portions of southeastern Florida that were once a part of the Everglades are now either heavily urbanized (in particular the area of the Atlantic coast from West Palm Beach south to Miami) or have been intensely modified for agricultural production.

Purple Gallinule

One final source of confusion is that the Everglades is often associated exclusively with one particular plant community: sawgrass marsh. Although sawgrass marsh is the habitat most characteristic of the region, and there are indeed vast areas of this particular community, Everglades is actually a complex and interdependent system that includes cypress swamps, hardwood hammocks, pine rockland, estuarine mangrove forests, and the marine environment of Florida Bay.

Crested Caracara

Approximately speaking, the Everglades is the area of southern Florida that includes the Kissimmee River watershed south to Lake Okeechobee, and the area south of the Caloosahatchee River and the St. Lucie Canal.

Snail Kite

Birdlife in the Everglades is weighted towards species with a lifestyle that is in some way aquatic (e.g. ducks, rails, herons, ibises), but there is a considerable abundance of passerine birds as well (e.g. tyrant flycatchers, swallows). Also well represented are birds of prey (e.g. vultures, osprey, hawks, kites and falcons) and pigeons & doves.

White-winged Dove

Also present in the Everglades is a growing list of introduced exotic reptiles, the most destructive of which are probably the Burmese Python and the Argentine Black-and-white Tegu.

What, Me Worry?
