Hawaiian Honeycreepers

A long, long time ago, a number of finches found their way to several remote, bird-less and unpopulated islands in the middle of the Pacific Ocean.  The archipelago's volcanic mountains contained tropical jungles with cascading waterfalls along with dry forests sloping to the coasts and beaches.  These stranded birds found plenty of nectar or seeds to sustain them and over millennia multiple new species of birds evolved from their descendants by adapting to the specific diets and habitats available on the different islands.  Later generations of the original finches became the large and diverse family of Hawaiian honeycreepers. With widely varying colors, bill shapes and sizes, the honeycreepers were especially prized by the first human settlers, the Polynesians, who landed on the islands almost a thousand years ago.  The rich reds, bright yellows and stark blacks of the birds' feathers were used to decorate the cloaks and adornments of the most important tribal le...

The White-tailed Tropicbird in Kauai

What strikes you most about the birds you initially see in Kauai and the other Hawaiian Islands is that there are so few native species.  At the airport, along the coastal roads, and throughout your hotel's manicured landscape, you're going to immediately see myna birds, a type of starling from India that's filled some of the void left when many native birds died off from the mosquito-born diseases that reached the island with western visitors in the nineteenth century.  And unique on the Garden Island, as Kauai is nicknamed, are the countless feral chickens noisily and aggressively begging for food.  Of course the equally numerous cats make you wonder why it's not referred to as the Kat Island! Nevertheless I was pleased to encounter one local sea-going bird within a day of arriving on Kauai.  The white-tailed tropicbird has probably been visiting since before the original Polynesian settlers reached the Hawaiian archipelago almost a thousand years ago.  Li...

The Most Colorful Lizard in Arizona

One of the greatest pleasures of birding is bearing witness to the kaleidoscope of colors in the subjects: the iridescent amethyst of a Costa's hummingbird's gorget, the azure of a blue grosbeak's head and torso, the chartreuse of a green-tailed towhee's wing and tail feathers, and the all-encompassing scarlet of a summer tanager.   While enjoying this pastime in the idyllic outdoors of Arizona, you're bound to see an equally vibrant range of hues in the abundant wildflowers and butterflies that populate the landscape, and to a lesser and more subtle degree, in the reptile population. Lizards and snakes are usually best known for the intricate patterns in their scales of their skin, the most famous of which might be in the aptly named diamondback rattlesnake.  These designs are often unique enough to identify specific individuals.  However reptiles are also quite colorful, as seen in the red stripes of some king snakes and the pinkish orange of Gila monsters. ...

Praying Mantises in Prescott

As a child in suburban New Jersey in the early seventies, summer fears were numerous: shark attacks down the shore, thunderstorms that kept you housebound for longer than an hour, and going to federal prison for killing a praying mantis.   In reality, shark attacks were almost unheard of until the blockbuster "Jaws" fed the rumor they were a regular occurrence, while our neighbor's wrap-around porch provided a safe and dry playground in inclement weather.   And the idea that the praying mantis was so endangered or such a valuable tool in the fight against agricultural pests was just an urban myth.  It seems that fact wasn't disproved the same time I stopped believing in Santa Claus, the Easter Bunny and the Tooth Fairy, as I just discovered the information on Snopes.com, the well-regarded fact-checking website.  Praying mantises or mantids  show up at my Prescott home late every summer.  In fact. this past week exactly three individuals appear...
