Where We Bird — Rio Negro

Walk with us into the tunnel of ‘To-le-do’, the song of the Lance-tailed Manakin. A superstar of San Vito birding, this active and beautiful bird also makes a mewing, catlike call. The red cap, blue back, tiny tail and orange legs make males unmistakeable; females are greenish, as are all the lady manakins, but she does have that tail! Here, they are only found at our southern Pacific border with western Panama but their range extends from Costa Rica to

Venezuela. Inhabiting the humid and second growth forests, Chiroxiphia lanceolata males are active at leks from Janury to March. Excellent and acrobatic dancers, you can find them on YouTube but, really, why not come here and see for yourself?

Bicolored Hawks can be found all around Costa Rica but they are categorized as ‘rare’. Luckily for us, they are regularly seen at this site or from the car on the way! The rufous thighs are diagnostic in adults but the juveniles are easily confused with forest-falcon species.

These raptors prey on birds, diving after them from perches at any height in mature, wet forests and tall secondary growth — even forest edges and gardens. They are in the same genus with Sharp-shinned and Cooper’s Hawks in the north.

Finally, we come to a bird found at lower levels of the forest following ant swarms: Bicolored Antbird. Plump and endearing with a big, blue eye-ring, it’s hard not to want to scurry after them. This species is said to have been the favorite of Dr. Alexander Skutch, author of ‘A Guide to the Birds of Costa Rica’ with F. Gary Stiles.

Where We Bird — the Wilson Botanical Garden

The San Vito Bird Club’s roots are here in the Robert and Catherine Wilson Botanical Garden at the Organization for Tropical Studies Las Cruces Biological Station — this is a long name for a magical place. Birders come from all over the world to this spot with its list of half of the country’s land birds. We have been offering bi-monthly Bird Walks here, free and open to the public since 2004, binoculars included!

In and around San Vito, we have many ‘specialties’ — birds not easily found elsewhere. Two of the most sought-after are reliably found here where you can stay in comfortable cabins with three meals a day included, a birder’s dream destination.

The Ruddy Foliage-gleaner can be found in early morning at the beginning of the Rio Java Trail. The best way to find it is to learn the call as it is usually vocalizing as the flock moves along the forest edge.

Another, smaller beauty — the White-crested Coquette — is also here in the Pollinator Garden and can be found at virtually any time of day. It is endemic to southern Costa Rica and western Panama

from the canopy to forest edge and gardens. You’ll have to be on your game as this exquisite creature is ‘bee-like’ in flight.

We are sure these coquettes are stealing your heart and reminding you to clean your binoculars.

Continue to scroll down from here to see just a few more photos from of this special site. The lovely garden vista was designed by Roberto Burle-Marx, a renowned Brazilian landscape designer who was a board member of the Wilson  Garden in its very early days.

This is followed by the Canopy Tower donated by the SVBC in 2011. If you get lucky up there, you might even see a field mark on a fast-flying swift.

Zooming With Owls — Part 4

Of the five species of Screech-Owls in Costa Rica, we are lucky to have two in our corner of the southern Pacific: Tropical Screech-Owl and Chocó Screech-Owl. Fairly commonly heard (and seen) in San Vito is the Tropical, with two color variations. Seen here is the gray version (of four sightings spread over 20 years, the author claims three of them were the rarer rufous morph). An important field mark is the facial disk outlined in black.

These endearing creatures are small, about 9″, and can be found in forested areas along with gardens and city parks. They pounce on prey from bare, low branches favoring large insects, spiders and scorpions (!).

Chocó Screech-Owl (Megascops centralis) is harder to find and was formerly known as Vermiculated Screech-Owl. With some perseverence, you might find one a little lower down the ridge toward Cuidad Neily. A good field mark for the Chocó is its lack of a distinct facial disk and less vertical streaking on the breast.

When we asked the Screechies if they found it difficult to sleep during the day, the Tropical said (click here and press play to listen), “Yes, because you humans are constantly taking pictures of us” — in Owlish, of course. On the other hand, the Chocó (click here) said, “No, because we know where to hide.”

Zooming With Owls — Part 2

Everybody loves owls, no? Yes! They are particularly endearing and, with their round heads, round bodies and big eyes, they almost look like Bobblehead Toys. The problem is we need to go out at night to see them or have a spectacular bit of luck on a daytime bird walk.

Mottled Owls are the most commonly heard of them all in San Vito. You can often hear them start to call at dusk or later into the night and they sound a little bit like dogs in the distance until you accustom yourself to their voice. They start breeding in February and, when two of them get each other wound up — calling back and forth — it makes a big, kind-of-scary, duetting racket!

Apparently there is a question on the correct scientific name of this owl. According to the Taxonomy Seer of the SVBC Jo Davidson, in Costa Rica we use Ciccaba virgata. You will see it referred to as Strix virgata in the links below. In either case, or both, Mottled Owls are found from Mexico to Ecuador, Bolivia and Argentina.

The larger Black-and-white Owl is far less common but has been reliably seen and heard near the forested area around the Las Cruces Biological Station. It takes bigger prey than its cousin, feeding on small rodents and bats in addition to large insects favored by both.

You won’t be surprised to learn these owls are in the same genus with their similarly rounded shape, no ear tufts and prominent, fancy eyebrows. Ciccaba nigrolineata is the Black-and-white found from Mexico to Venezuela and Peru.

Let’s see what they have to say for themselves when asked about swiveling their heads around to nearly 180 degrees: is it fun? It looks like a conjuring trick! Click the link here and press play to hear the Mottled Owl’s reply. It sounds like it is saying, “Wow, wow, wow!” And the Black-and-white had this to say: click and press play. This sounds like “Just who are YOU?” to us.

And finally here are both of them arguing over the answer; see if you can tell who is calling by clicking here!
