First Sighting of Green-winged Teal by Birders
in Costa Rica!
The
new millenium certainly started off with a bang! After all the
fireworks and hoopla over Y2K had faded away, I took my children
out to Finca Las Concavas (between Cartago and Paraiso) to look
for a Northern Pintail that had been reported there during the
Cartago Christmas Bird Count, held December 19, 1999. Our outing
took place on January 4, 2000 -- a little more than two weeks
after the count -- on a partly overcast but generally pleasant
day, especially considering all the rain that the area received
during December and January.
Many
who visit Las Concavas bird around the large pond visible from
the entrance road, but our experience has been that there is far
more "action" at the tiny pond below the dairy barn (turning right
and staying behind the houses after passing the guard house).
And it was the small pond we checked first in hopes of finding
a duck that would have been new for us in Costa Rica -- never
dreaming what we were about to discover!
It
was Leonardo, my oldest son, his eye at the telescope while panning
through scores of Blue-winged Teals, who made the discovery. "Hey!
Look at this!" he shouted in astonishment. One by one, we took
our turn at the eyepiece to marvel at a cracking male Green-winged
Teal calmly standing on the far bank of the pond, flanked
by blue-wings.
According
to the account in A Guide to the Birds of Costa Rica
by F. Gary Stiles and Alexander F. Skutch, this species had been
known in the country on the basis of one banded bird shot at Ochomogo
in 1962 and "several unconfirmed reports by duck hunters of birds
shot in Tempisque basin." As we stood admiring the bird, I called
Julio Sánchez, curator of birds at the National Museum
of Costa Rica, to report our find and inquire if he knew of any
other reports since the publication of the field guide. The answer:
Negative.
It
was one of those rare incomparable moments as the awareness set
in that we were undoubtedly the first birders ever to observe
this species in Costa Rica!
Since
this was literally "a sitting duck" and the chances were very
good that it would not leave the spot, that evening I began making
phone calls and sending e-mails to local birders to get the word
out. During a phone conversation just the other day with Robert
Dean, he informed me that he visited Las Concavas in mid-March
and the bird was still there. Jim Zook, who went to see "our"
Green-winged Teal shortly after the discovery, saw another male
of the species at Palo
Verde National Park in February! He also thought that someone
had seen another individual somewhere else this year -- when it
rains, it pours. I'll try to follow up on that report in the next
newsletter.
By
the way, the Northern Pintail report that started this whole thing
turned out to have been an error on the entry log!
Male
Painted Bunting Makes Backyard Appearance
A scant
four days after our encounter with the Green-winged Teal, David
(one of the twins) was birding out in the yard when a male Painted
Bunting flew in to one of the Gumbo-limbo (Bursera simaruba)
trees along the back property line. News of the sighting came
bursting through the windows like bricks hurled by demonstrators
and those of us inside went scrambling for binoculars and the
nearest exit.
Once
outside, we awed at the bird's beauty as the afternoon sunlight
illuminated every detail of its fine plumage. A life bird for
everyone in the family but me, it was also a new yard tick that
currently has our house tally at 121 species in eight years of
living here on the western edge of San Antonio de Belén.
Lifer
Takes Backseat to Out of Place Antbird
January
was worrisomely slow for tourism here in Costa Rica, as perhaps
it was for much of the world since the blame was placed on the
great Millenium Bug (Diurnata interrupta), a malicious
nuisance of pandemic proportions. Thus, I was understandably relieved
to receive word that a two-week tour with Full Circle Tours had
confirmed for February -- albeit with just two people.
The
trip got off to an auspicious* start as we traveled to Limón
and then up the canals to Tortuguero on February 13. We had just
entered Tortuguero
National Park from the southern entrance at Jalova and were
enjoying the jungle ambiance of the narrow, winding waterway when
our boatman, Modesto Watson, cut the throttle. Following his instructions,
our attention was brought to a Green Ibis sitting on a nest. From
what we could see, the nest consisted of a platform of twigs placed
on a horizontal portion of a Raffia palm (Raphia taedigera)
frond about three meters above the water. I mention this because
as of the publication of the field guide, the nest of the Green
Ibis was undescribed (although I strongly suspect that nearly
every native boatman in the Tortuguero region has long known what
one looks like!).
Several
days later, our itinerary had us in Guanacaste where we visited
Santa
Rosa National Park at dawn on February 18. Coming in the paved
entrance road from the PanAmerican Highway, we spent more than
an hour birding the patch of primary forest encountered at about
five kilometers in from the park entrance. The birding was quite
entertaining with a good variety of native species and North American
migrants, although the mutually agreed highlight was the performance
of the Long-tailed Manakins -- two males and two females that
allowed us the privilege of witnessing their entire courtship
song and dance routine THREE TIMES!
Between
the bouts of manakin antics, a bit of flock activity materialized
just a few meters down the road and as I approached to get a better
view an Ivory-billed Woodcreeper came working its way up a small
tree trunk at eye-level. A life bird! And along with the Gray-fronted
Dove, the only dry forest species in Costa Rica that had thus
far managed to avoid my gaze.
At
this stage in the game (723 spp.), life birds in Costa Rica tend
to be few and far between and, thus, usually all the more to be
savored. My elation lasted less than a minute, however, as another
bird caught our attention almost immediately. It was an immature
antshrike foraging in vine tangles on the other side of the road.
It came in and out of view, but each time that it was briefly
visible I became more and more certain that it was a Western Slaty-Antshrike
-- a bird that should not be in the northern Pacific dry forest!
As lately I've taken quite an interest in bird distribution and
status throughout the country, I was far more impressed by this
juvenile out-of-place antshrike than I was by a bird which was
perfectly at home in the habitat, even though I had never happened
to have seen it before!
As
a postscript to this story, upon returning home from the trip
a week or so later, I checked my mailbox at the local post office
and found the Spring 1999 (sic, it's a long story) edition of
Cotinga, the Journal of the Neotropical
Bird Club. And whaddya know? There on page 21 was an article
by Mark W. Lockwood, "Occurrence
of Western Slaty-antshrike Thamnophilus atrinucha on the Pacific
slope of Costa Rica." On March 8, 1998, he observed and photographed
a pair of adult birds in the same patch of evergreen forest.
I
guess we got to see Junior.
*Do
you know the etymology of the term "auspice"? According to my
Random House Dictionary of the English Language,
it derives from the Latin "auspicium a bird-watching,
divination from flight of birds = auspic- (stem
of auspex one who observes birds, soothsayer) +
-ium noun suffix."
A
"Pearl-less" Journey to San Isidro
From
mid-March through early April, Costa Rica was plagued by outbursts
of social unrest resulting from a general discontent with a controversial
new telecommunications/ power-generation bill being debated in
the Legislative Assembly. The sporadic roadblocks that appeared
on various of the country's main thoroughfares made for difficult
and unpredictable traveling. For reasons I'm not really sure of,
the town of San Isidro del General was one of the most ardent
centers of dissent.
It
was also one of the places I had most wanted to visit since my
son Leonardo had attended the Birding
Club of Costa Rica's outing to the area in mid-February.
Following
a morning visit to Los
Cusingos -- Dr. Skutch's farm -- a few of the keener participants
spent the afternoon birding on the grounds of their hotel, the
Talari Mountain Lodge. It was in an overgrown pasture with scattered
trees down by the Río El General where they saw a Pearl
Kite "sitting high in the branches of one tree for several
minutes before disappearing into the denser leaves of an adjacent
smaller one. Very close investigation failed to flush it, making
us suspect it had fled unnoticed, yet when we eventually decided
to give up, it took the opportunity to fly out, landing on an
exposed branch some twenty feet up in another tree, affording
us our best views yet . . . . Meanwhile, George Wallace had been
vigilantly scouring the tree in which it had remained silently
for so long and discovered a nest, attended by our bird's mate!"
(from Robert Dean's trip report).
This
handsome little raptor has been working its way north on both
sides of Costa Rica during the last ten years, but this is apparently
the first report of an actual nest in the country. Jim Zook did
observe what appeared to be pre-nesting courtship behavior a year
earlier in the area of Palmares, just a few kilometers southeast
of San Isidro, but found no nest.
And
speaking of Jim Zook, his phone call on March 13 was the REAL
reason for my desire to get down to the San Isidro area. That
very morning, he had seen three Southern
Lapwings in a field near the El General sugar mill. (And to
sweeten the pot, he also mentioned seeing Red-breasted
Blackbirds and a Pearl Kite in the same area-all three of
these species would be new for my Costa Rica list, and the former
two would be lifers.)
Actually,
in a curious way I have seen Southern Lapwings in Costa Rica:
while sitting on my living room sofa! I was watching a locally
produced nature/travel program in May of 1997 when up came full-screen
images of a pair of Southern Lapwings standing on a gravel bar
in the middle of the San Carlos River up near the Nicaraguan border.
The announcer mentioned that these birds were not to be found
in the field guide, and I thought to myself, "You bet they're
not!"
A
phone call to Julio Sánchez the next morning confirmed
that this was apparently the first country record of the species.
The following year, birders staying at the Laguna del Lagarto
Lodge again observed this species when they did a boat trip on
the same stretch of the river. Although I don't know the date,
it must have been in the first half of the year because I saw
the photographs in July of 1998.
Finally,
on Saturday, April 1, 2000, I decided to take advantage of the
fact that the protesters seemed to be taking the weekends off
and made my pilgrimage in search of these three ticks. With the
four boys loaded up, we pulled out of the gate at 4:00 and were
up at Km 96 by 6:00, enjoying a crystal clear morning on Cerro
de la Muerte. By 7:30, we were pulling into the rustic roadside
restaurant "El Trapiche de Nayo" situated at about 1050 meters
above sea level and just about 15 minutes away from San Isidro.
We had trouble ordering breakfast though, not because the menu
was extensive (there was a choice of gallo pinto any one of three
ways), but because there was so much bird activity just off the
balcony that I could hardly get the kids' attention. To make matters
worse, we discovered that we were in the middle of hawk migration
and small kettles of Broad-winged and Swainson's Hawks kept swirling
up from below and passing right over the restaurant. The real
breakfast-stopper though was a Black Hawk-Eagle that came right
in just above eye-level, glided over the building, and disappeared
over the ridge across the highway. Great looks and a lifer for
the boys!
Niy
minutes and thirty-seven species later, we resumed our journey.
We
spent an hour looking for the lapwings et.al. along the short
stretch of road from the PanAmerican Highway to the sugar mill,
but alas with no luck. Although we did see 40 species including
a couple of lifers for the younger fellows: Fork-tailed and Bran-colored
Flycatchers. One amusing moment came when a Swallow-tailed Kite
was harassed by a Fork-tailed Flycatcher giving the impression
of being a contest to see who had the longer tail!
Arriving
at the Talari Mountain Lodge just before noon, we birded a bit,
had lunch, and then went off in search of the "resident" Pearl
Kites. We stood under the nest tree (though I confess to not seeing
an obvious nest) and wandered the grounds along the river, having
a nice look at a female MacGillivray's Warbler and an entertaining
variety of tanagers, but no kites. Having already seen eight species
of raptors that day (with a crippling view of a pair of Bat Falcons
dining on a too-dissected-to-identify bird still to come), I had
felt sure that the Pearl Kite would be no problem. To further
rub it in, the owner of the lodge told us that a group of birders
had seen the kites from the swimming pool that very morning.
Well,
at least I felt good for having made the effort. It would have
been far worse to have lived with the thought that I didn't even
try. And, of course, there's always a next time.
Winnie
O. Scores Big at La Virgen del Socorro
On
March 16, Winifred (Winnie) Orcutt rang to report a goodie she'd
seen that day at La Virgen del Socorro: a Lanceolated Monklet!
It was sitting on a low branch less than 100 meters in the forest
trail to the right just before you reach the old bridge over the
Sarapiquí River-in other words, apparently the same spot
where at least a half dozen other fortunate observers have encountered
it.
I
visited the LVS road on March 29, but due to time constraints
didn't make it that far down the road (sigh). We did have an army
ant swarm marauding right beside the track with at least six Immaculate
Antbirds in attendance. Great views! It was fairly open in the
understory and I thought we might get to see all sorts of other
things attracted by the commotion, but only logged one Slaty-backed
Nightingale-Thrush and a Yellow-bellied Flycatcher.
Word
of a Possible New Species for Costa Rica
Rafa
Campos called on Sunday evening, April 2, with third-hand news
of a Clapper
Rail report. The way I got the story is that a group of North
American birders saw this species somewhere along the Tempisque
River. Hopefully, Julio Sánchez will have more details
that I'll be able to report in the upcoming edition of this newsletter,
but he's currently off on a field trip.
That's
Nidicolous!
And
finally, I thought I'd pass along this little tidbit that I stumbled
upon while surfing for an image of a Western Slaty-Antshrike (which,
by the way, you'll have noticed was not an image, but a sound
clip and a brief mention of why this species is no longer called
Slaty Antshrike in Central America). It's an abstract
of the paper: "A test of the Skutch hypothesis: does activity
at nests increase nest predation risk?" published by J.J. Roper
and R.R. Goldstein in Journal
of Avian Biology, No. 2, June 1997 (ISSN 0908-8857).
I hope
that you've enjoyed this newsletter and welcome any comments at
gonebirding@lycos.com
or if you're in Costa Rica, feel free to give me a ring at 293-2710.
Wishing
you all a great spring migration,
