GET YOURSELF TO ECUADOR

July 21, 2017

PIB has great trips to various habitat zones in Ecuador. And there’s a book you want to take with you. It’s the first-ever, one volume nature guide for anyone headed to Ecuador’s wondrous mountains and rain forest and arid western slopes:
Wildlife of Ecuador:
A Photographic Field Guide to Birds, Mammals, Reptiles, and Amphibians

Andrés Vásquez Noboa. Photography by Pablo Cervantes Daza. Princeton Press. 2017. $29.95.
I wish I’d had a book like this when I was in Ecuador…or even Panama where I got far too close to a pit viper without recognizing it. The bird section is fine but the real value is in all those other critters: face-to-face shots with snakes. It’s the head that matters…look for the heat-sensing pits. You may want to keep your birding guide nearby or back at the ecolodge because only breeding plumage shots are given for most avian species.
Now I know there are two species of agouti in Ecuador and I saw the black in Coca. Not sure even my bird guide knew there were two, certainly didn’t tell us.
Superbly clear range maps. Both English and Latin indices.
My favorite Ecuadoran bird is at the top of page 140…the Collared Inca.

OF EAGLES AND SUCH

July 18, 2017

Harry Fuller writes: Recently a long-time friend, Dr. David Sachs of Palo Alto, sent me a great photo of a fish eagle taking a fish from a lake in Zimbabwe. He asked a little about the eagle and I inadvertently buried him in data.
David, I got your recent note with the action shot of the African Fish Eagle. Kate and I saw this bird several times around the lakes in Uganda. Handsome bird. Yes, the fish eagle would carry food back to brooding mate and then to young after they hatch. The nest would never be left unguarded once the first egg is laid. And the nest has to be protected from such possible nest thieves as Red-tailed Hawks and Canada Geese. Even winter nesting Great Horned Owls are known to steal an Osprey’s nest that has been years in the building. The owls nest even before many Osprey have returned to their nesting territories. Many large birds (storks, eagles and osprey) will usually return to previous year’s nest if they can, and simply repair and remodel. Then young eagles will spend over a month in the nest before they can even begin to try short flights and then they are fed wherever they perch after leaving the nest. To become an adept predator a young bird needs lots of practice and parental support. At least their “college” is free.
The African Fish Eagle is in the same genus as our own Bald Eagle and the White-tailed Eagle of Northern Europe. They are all in Haliaeetus genus. Haliaeetus is a compound of two Greek words, translated literally as “sea eagle.” Our Bald Eagle is not really a “sea eagle,” more strictly a bird of marsh, lake and river though it will fish in quiet salt-water lagoons and estuaries. The fish eagle is smaller than our Haliaeetus eagle and the European one. It is less than thirty inches tall. An adult Bald Eagle will be at least 31 inches tall and the female (which is always the larger of the pair) can be over three feet tall with a wingspan up to 7 feet or more. Our Bald Eagle does fish but in winter often lives on carrion from dead waterfowl as large as swans. This eagle has evolved an immunity to avian cholera and botulism which is handy in winter when large number of migrants waterfowl sicken and die on any over-crowded wintering range.
I have always though the Bald Eagle—contra Benj. Franklin who favored the Wild Turkey—was a perfect symbol for our money-mad country. This eagle will catch its own fish but often uses theft, bullying or simply good luck to find food. Other birds’ diseases leave carrion for eagles, ditto road kills. An eagle pair is great at ganging up on a hard-working Osprey (almost a pure piscine feeder) and stealing its fish. I have also seen eagles take ground squirrel away from Red-tailed Hawks. The Bald Eagle is sort of a hedge fund manager looking to make off with anybody’s else’s hard work or profit for its own selfish good. They are pretty good parents, of course. But among adults there is only begrudged sharing of a carcass. Often one eagle will have found carrion and a coterie of ravens will land just out of reach, waiting for the scraps. The Bald Eagle has one other great strength which is its great strength. It can easily remove bits of frozen deer or goose flesh from a hard-frozen corpse. Some scavengers like ravens and Turkey Vultures lack that strength. Eagles can winter anywhere there is food, fresh or frozen. However, the Turkey Vulture must migrate south to where the nights are warm enough to not freeze a carcass solid. On the Pacific Slope that is generally south of Redding or along the coast. Now, with global warming, a few vultures are wintering in Willamette Valley.
Our other native American eagle is the Golden. It’s a member of the large tribe in the Aquila genus. Aquila is Latin for “eagle” and especially refers to a sharply hooked beak. It is believed that “eagle” derived from old French word “agile” which in turn derived from the original Latin.
Our Golden Eagle has cousins all over the world, most smaller in size. The American Golden females can be up to 40 inches tall. Most of the Old World eagles in this genus are less than three feet and most are some shade of brown with little bold patterning (except the bright white on the Wahlberg’s Eagle). These are birds of mostly open terrain. Our Golden is a specialist in catching jack rabbits and other denizens of our grasslands and prairie. This bird takes talon strength to the max. It can muster several hundred pounds per square inch pressure when it grabs prey. It generally hits prey from behind and kills quickly by crushing the victim. They often nest high in tall trees or on cliff faces in dry areas where there are no trees. Nobody bothers a Golden Eagle in any serious way in daylight.
Two quick stories: I once saw a territorial male Osprey go about trying to drive off a Golden Eagle soaring over a hillside near the Ospreys’ nest. Twice the Osprey screamed and then dove down toward the eagle’s back…each time the eagle flipped over onto its back at the last instant and invited the Osprey to come on down. The eagle’s talons were open and waiting. Each time the Osprey swerved off at the last minute. Those talons would have meant a crushing defeat and death, literally.
A friend in Ashland lives out in the parched, grassy hillsides of the lower Cascades. The Golden Eagle and the Red-tailed both hunt there regularly. A pair of Golden Eagles were nesting on a rocky point uphill from my friend’s house. He often saw the smaller and more agile Red-tails harass the eagles as they hunted, hauled food to the young, built their nest. This is common in avian world—smaller, quicker birds pester bigger, slower predators. I’ve even seen blackbirds go after a vulture which eats only carrion. An angry hummingbird can drive off a huge raven. My friend was out on his hillside planting oak saplings to restore the chaparral that was once there. He saw a Red-tail swoop down the slope and nail a California ground squirrel. Then the hawk tried to get a good grip to haul away its fairly weighty prey. Shortly my friend sensed a big shadow speed by and looked up to see a Golden Eagle hit that Red-tail from behind. Astounded, he watched the eagle tear apart the hawk and the squirrel, fairly efficiently, then fly off. Nothing was left on the ground but shredded bits of both creatures. Apparently the Golden Eagle was settling an old and bitter score.
“Eagle” is an old English word thrown around in naming many unrelated species in the Old World. Some eagles there would be simply big “hawks” here. We would not consider a bird less than two feet tall worthy of that grand a moniker. There are even now birds commonly named “hawk-eagle,” go figure. Perhaps the most striking of the African eagles is the Bateleur, 28 inches tall. In the Old World “buzzard” is synonymous with “buteo,” the genus of our Red-tails. “Vulture” in old world is a group of large predatory birds, not strictly scavengers like our vultures and condors who are actually well-adapted members of the stork family, unrelated to Old World vultures. So it goes in the world of taxonomy vs. common lingo.

Here’s my own shot of a pair of fish eagles perched in a forest in Uganda, taken on an PIB-sponsored trip:FISH EAGLES

BIRDING AUSTRALIA?

June 30, 2017

Review of  “The Australian Bird Guide” by Peter Menkhorst, et al. 560 pages. Over 240 color plates. Princeton University Press.  paperback. 2017.  $39.95.

Harry Fuller writes: Long separated from the nearest major continent, Australia has many endemic species and is a birder’s wonderland for all the lifers awaiting you there.  I have never been but my good friend and fellow bird-nut, John Bullock and his wife Stephanie visit there often.  Their son lives there with his family.   So here is a review of Princeton latest guide to Aussie birds, by guest reviewer, John Bullock:

Australia Bird Guide Review
If you’re an Australian birder, with the challenge of over 900 species to
identify, your choice of guidebooks has recently been expanded by the
production of The Australian Bird Guide, a stunning and very complete work of
art and science, the making of which has consumed over ten years, involving
over 200 citizen contributors (think eBird on a small scale).
The impetus for a fresh guide to Australian avifauna was initiated by the
head of the Australian Scientific Research Organization, who secured the services
of Jeff Davies, one of the country’s pre-eminent bird illustrators. Jeff was joined
by five additional authors and illustrators.
Historically, avian artists have depended on museum skins for their
guidebook renderings. Enter digital photography, and a large number of birders
eager to capture pixels of every species in every imaginable pose, in all of their
plumages. For Davies and his partners, this turned out to be a bonanza of over
half a million images.
There are 56 species of Honey Eaters in Australia, many of them very
similar. The digital images have resulted in more accurate illustrations: an
improvement much appreciated by the more determined birder faced with a
Honey Eater, that at first sighting, could be one of ten or twelve similar species.
The guide, in addition to being an amazingly brilliant and vibrantly
detailed collection of illustrations, retains the essential elements of proper
ornithological and taxonomic protocol, as well as the valuable information on
where and when to find Australian birds.
Australia is a unique continent, noted not only for its flora and fauna, but
also for its people. Visitors are always impressed by the friendly open-ness of
Aussies. Having had the fortune to spend part of the past five years there, I can
vouch for this impression, and enlarge it by noting that Australians are very
proud of their relatively young culture and eager to learn about and protect their
environmental heritage. The Australian Bird Guide fits this picture perfectly. Its
a fresh and compelling addition to Australian birding literature, and I look
forward to using it during my upcoming annual sojourn.

BIRDING WESTERN ECUADOR?

July 4, 2016

Here is a great reason to go birding in western Ecuador.  This is the endemic White-tailed Jay:White-tailed_JayAnd now the Princeton University Press has issued a photographic guide to the birds of Western Ecuador.  Living here in the Pacific Northwest I first notice the birds that aren’t found in this part of the Neotropics.  No scoters, no alcids. But then you settle in to thumb through the book and you notice 8 raptors named “kite,”  over 20 members of the dove/pigeon family, three pages of tinamous and guans (think big pheasants in the forest).  Toucans, barbets (my favorite gang of tropical thugs), hummingbirds for page after page, Tanagers, endless tyrant flycatchers, antwrens and antvireos and antbirds,  Finally near the back of the book you get to the euphonias, dressed like a junior high marching band.euphoniaThis is a Thick-billed Euphonia.

The book includes range maps for each species showing its range across Ecuador.  The book does NOT include the Galapagos.   If you go after that White-tailed Jay, take this book along. Partnership for International Birding offers a panoply of birding trips to Ecuador.  Check ’em out.

SOME CONSERVATION NOTES

January 8, 2015

Not-so-hopeful news from Brazil where a politician dubbed by some “chainsaw queen” has been named to a post where she will influence policy on deforestation there.

A brighter spot: the Pope has begun to openly push for more action to curb climate change.

And there may be help on the way for Europe’s glorious, huge Griffon Vultures.  A veterinary chemical that is deadly to the birds is beginning to get banned in some countries.  The drug: diclofenac.  If you’d like to see a Griffon Vulture in France or Spain, PIOB can get you there.

And here in the U.S. the Red Knot has been put onto the list of threatened species by the federal government.

RAPTOR RECORD OVER PANAMA

November 21, 2014

This fall’s migration saw a record number of raptors passing over Panama City in one day. Take a guess, then click on this link and read about the number of zeros in the new record.
PIB offers great trips to Panama, including a chance to see Harpy Eagle.
But Panama is much more than just raptors…below some images from my recent trip to Panama: Violaceous Trogon, white-faced monkey and White-necked Puffbird.

OAKS OPENINGS, LAPLAND AND MISSISSIPPI

May 9, 2014

Oaks openings sounds like a twee name for a 3600-acre open space preserve, but once you start birding there it could be named “Walmart” and you wouldn’t care. Great spring birding. Warblers included Canada, Wilson’s, Chestnut-sided. And these guys, as well:

CALIFORNIA DREAMIN’ FOR NEXT SEPTEMBER

January 9, 2014

I will be leading a trip along the California Coast next September. It will be at the height of shorebird migration: Black Turnstone, Wandering Tattler, Red-necked Phalarope, Surfbird, Marbled Godwit, various sandpipers and plovers. Click here for itinerary.
Of course, we will cruise along Big Sur, a magnificent coastal highway, in search of North America’s largest bird (by wingspan).CONDOR3

CONDOR4
These Condor pictures were taken on the same route a couple years ago. There are now more condors flying free than are in captivity. A remarkable story of saving an endangered species that once got down to less than 20 individuals.
