Big-beaked birds – lovely or laughable?

I don’t know how many of us would find a human being with an extremely large nose (e.g., even bigger than the face) and multi-colored head, facial and body hair to be beautiful or even attractive. Perhaps it would depend on the nose shape and which color combinations would be in play? But it is certainly a fact that many of us find big-beaked, multi-hued birds to be alluring and enticing, if not just plain gorgeous, magnificent and delightful to say the least.

Well, Costa Rica does not lack for a variety of big-beaked birds and I found them all appealing, each in their own way. Some were not completely colorful but had splashes of color, like the brown-hued Montezuma oropendola (Psarocolius montezuma) with its white bare patch on the cheek with a pink wattle underneath and mostly yellow tail feathers.

An unusual fact about this bird is that the males are generally twice as heavy as the females. They are called “colonial” nesters, meaning that the females build their pendulous nests (24-71 in/60–180 cm long) near one another in “colonies”. Unfortunately, their nest success is not great with only about one-third of colony nests resulting in a fledgling!

 

These oropendolas tend to forage in small groups in the tree canopies, searching for insects and fruit. Their love of fruit also brings them to feeding platforms, like this one set up to not only entice birds but also the tourists who want to see them. They seemed to especially enjoy papayas and watermelon.

The call that the males especially emit from their bi-colored black and red-tipped beaks is said to resemble water being poured from a bottle, bubbling and gurgling.

The chestnut-headed oropendola (Psarocolius wagleri) resembles the Montezuma species but is a bit less colorful with a pale bill. They are a bit smaller than the Montezumas and fly more quickly. Like their cousins, their broods in hanging nests are also threatened by giant cowbirds (nest parasites) and botflies.

 

We were lucky to see two toucans and a toucanet during our trip to Costa Rica this past year. We had a glimpse of a keel-billed toucan (Ramphastos sulfuratus) high up in trees on a cloudy day. Their large bill measures 4.7-5.9 in (12–15 cm), which is about one-third the size of their entire length! Their zygodactyl feet (two toes facing forwards and two facing backwards) help them balance on branches.

 

We got an up-close and personal view of a couple when we visited a hotel with an adjacent bird park and animal displays. A couple of these birds were in a large aviary, accompanied by two attendants who let people pose for photos with them. I just took photos of the birds and did not have a self-portrait done.

The second toucan that we got to see was the yellow-throated toucan (Ramphastos ambiguus), one of whom seemed to be posing for us during an early morning walk. They have an even larger bill than the keel-billed toucan, which ranges in length from 5.1-7.9 in (12.9-20 cm).

 

 

In 2018, I was able to photograph a couple that were flying by over a river.

     

 

The Northern emerald toucanet (Aulacorhynchus prasinus) is a smaller toucan that also sports a large beak in comparison to its head size. We saw one of these birds every morning at one hotel where we stayed as it was hanging out in trees next to our room cabins. It was often overcast, however, and it wasn’t easy to get a good photo; the same situation arose several days later when we saw one on another rainy day.

 

Luckily, that bird came down to a feeding station set up to attract birds for tourists. You can see its beautiful green body set off with a multi-colored bill that has a distinctive white band at the base.

 

Like other toucans, the toucanet will eat insects and lizards but it, too, has a real fondness for fruit meals, especially berries.

 

In contrast to the oropendolas, this bird’s calls resemble frog croaking and barking!

Unfortunately, it appears that these birds are popular as pets and they are taken from the wild to live in cages. They are popular because they can be affectionate and interact with their “owners” and they can learn tricks.

 

Going back to the bigger birds, Costa Rica has two aracaris, which are also members of the toucan group. They differ from other toucans in their sociability, often roosting in groups of several birds.

We did not see the fiery-billed aracari (Pteroglossus frantzii) during our August 2019 trip, but I had seen one flying by during a trip to Costa Rica in 2018.

It looks similar to the collared aracari but is distinguished by a bright red breast band and its bill is somewhat more colorful. It, too, is mainly frugivorous.

 

The collared aracari (Pteroglossus torquatus) was a frequently seen bird during our August trip through Costa Rica.

 

 

 

 

We visited several spots where people were earning tourist dollars by setting up feeding stations with plenty of fruit to attract a variety of birds. The aracaris were enthusiastic and voracious feeder visitors.

 

When the young aracaris are born, they are blind, naked and have short bills. Their feet also have specialized heel pads to help protect their feet from the rough nest floor. Not only the parents but also other birds help feed them for six weeks, at which point they fledge. The adults will still feed them for a time after they leave the nest as well.

These aracaris are interesting in that their large colorful bills also have a sawtooth pattern on the cutting edges. It can take up to a year for the young birds to develop the notches and color pattern on their beaks.

Now all these photos might give the impression that all the big-beaked birds are large in size, but this is definitely not the case. There are also medium- and small-sized colorful birds that tote around bills large in size when compared to their heads. Among the middle-sized range are two beautiful motmots.

We saw our first turquoise-browed motmot (Eumomota superciliosa) early one morning when it was still dark. A flashlight showed the bird sitting quietly in a tree as we made our way to breakfast. Oddly (to me at least), it didn’t seem very bothered by the bright light and just watched us as we drew near.

We later saw one sitting in a shady area alongside a road. They often perch on fences and wires as well, scanning the area for their diet of insects and lizards. They use their racketed tails for communication purposes, as part of a mating display or as a “pursuit-deterrent signal” to warn predators that they have been seen and will not be able to capture the aware birds. In Costa Rica, these birds have the nickname pájaro bobo (foolish bird) because they will allow humans to get quite near.

         

The broad-billed motmot (Electron platyrhynchum) is also an insectivore and has not been seen consuming fruit. These motmots are less studied than the turquoise-browed species; for example, it is not known how they use the tail rackets for communication.

 

The smallest bird in this account of the big-beaked avians is the rufous-tailed jacamar (Galbula ruficauda), which I first thought might be a large hummingbird. (Some hummers also have enormously large bills and will feature in a later blog.) They measure only 10 inches long (25 cm) with a 2-inch (5 cm) bill.

They are insectivores who will remove an insect’s wings before they swallow it. A surprising finding for me was that they nest in bare earth burrows. They do not keep the burrows clean and the nestlings do not lie down but remain standing so that they protect their feathers from accumulated debris!

On that surprising note, I wish my blog readers a wonderful start to the next decade and hope you all will have a great 2020 with good health, a comfortable living situation and as many hours enjoying our beautiful natural world as possible!

Costa Rican rambles 5B: the Talari Mountain Lodge and environs

 

After fully experiencing the “honey dew” (another name for cicada urine), we set off for the next university site, an area where students learn about planting. A statue of the Virgin Mary welcomed visitors and we admired some of the beautiful plantings and their seeds that were attracting plenty of insects.

   

 

We then left to make a quick stop at a park called Los Cusingos, that we would visit at length later; this was just a quick bathroom break before we took to the road again. My photo of the gray-headed tanager was not that great but you can see how beautiful the red passionflower (Passiflora vitifolia) at the entrance was.

As we drove to a place called Las Nubes, we passed private homes with their filled metal framework trash bins in front, a cemetery and plenty of banana plants.

 

   

One of our group members stepped in an anthill when trying to avoid puddles and traffic, which led to some stinging bites. In the meantime, others were trying to see various species of birds that were staying low in the vegetation along the road. I spotted a rather large wasp nest in a nearby tree, likely of the Synoeca septentrionalis species.

   

 

 

At some distance, there was a yellow-headed caracara (Milvago chimachima) sitting on a branch. These raptors are about 16-18 inches in length (41-46 cm) and part of their diet is carrion. They also eat reptiles, amphibians and other small birds, while avoiding birds as food. They take ticks off cattle as well, which gives them a thumbs up from me – any bird that eats ticks is a friend.

 

A gorgeous smooth-billed ani (Crotophaga ani) was sitting calmly as we milled around in the road. Some people might find this bird homely, but I think it is quite handsome despite a somewhat bulbous beak. They, too, are on my “good birds” list as they sometimes eat ticks and other parasites off of grazing animals. Another nice characteristic is their communal child-raising strategy – several pairs cooperate to build a nest together, in which several females than lay their eggs. They share the incubation and feeding of nestlings – hippies of the bird world!

 

We traveled on and the views along the road were beautiful, with the mountains and valleys in the distance and then we caught sight of some swallow-tailed kites (Elanoides forficatus) soaring over the nearest valley. We saw one land in a tree and it turned out that they were building a nest there. In the photo, you can see a small white patch on the right-hand side of the tree, which is the female kite on the nest.

As we waited patiently, a few kites began flying overhead; one with nesting material clutched in its claws.

 

They soared and swooped, giving us delightful views of their flight and then one came by with a meal that it had caught – a poor little chameleon or lizard.

 

We admired the Talamanca mountain range called La Amistad (Friendship), which separates Costa Rica from Panama. Starting in 1979, these two countries’ governments began a process to conserve the entire range, which is home to four indigenous groups of humans, 600 avian species, 215 mammal species, 250 species of amphibians and reptiles, 115 species of fish and some 10,000 flowering plants! As UNESCO has noted, this is: “one of the very few transboundary World Heritage properties, an excellent intergovernmental framework for coordinated and cooperative management and conservation.”

 

After a nice lunch, we continued visiting other sites, including one near a Canadian project. That afternoon, I saw my first trogon species – the gartered trogon (Trogon caligatus), another handsome bird to be sure.

 

      

While the rest of the group followed Steve’s instructions for sighting some birds hiding in underbrush on a slope, fellow traveler Janet and I watched some leaf-cutter ants (Atta cephalotes) at their labors. Sometimes, I was just not tall enough to see over shrubs to locate a bird and I love all wildlife anyway, so watching the ants in their industrious endeavor was fun.

On our way back to the lodge for supper, we passed small roadside stores and Steve spotted a fork-tailed flycatcher (Tyrannus savanna) for us.

 

 

Back at Talari, I did some sightseeing from the balcony of my room, spotting a lengthy and messy-looking flycatcher nest, a variegated squirrel (Sciurus variegatoides) traversing the tree canopy and a pair of palm tanagers (Thraupis palmarum), who were tending an offspring.

 

                       

At first, I thought the fledged bird was a different species as it sat under a leafy canopy, but later I saw the parents with it. Then it surprised Janet, who was staying next door – she called me over to see the fledgling who had flown into her room and was sitting in the middle of the floor.

   

She also had two nests under the roof of her balcony, one of which definitely belonged to a clay-colored thrush (Turdus grayi).

   

After admiring one of the neighbors’ cows and social flycatcher (Myiozetetes similis), I caught sight of a quiet beauty sitting on a branch in front of my room.

  

 

The Lesson’s motmot (Momotus lessonii), also known as the blue-diademed motmot, has a bright red eye and beautiful tail with what some birding sites call a “raquet tip”.

 

As we set off for the dining area, we were treated to a visit from a streaked flycatcher (Myiodynastes maculatus), quite a good-looking bird with its heavily streaked back, breast and face.

  

As we passed through some vegetation before dinner, I saw a gorgeous flowering banana as a blue-feathered and red-legged honeycreeper (Cyanerpes cyaneus) flew high overhead.

   

Even though we often were looking for birds in dark and leafy/shady areas, I avoided using a flash but when I saw the lemur anole (Norops lemurinus) on a tree, I gave in so that I coul d get a photo.

 

As dusk came on and we looked out from the dining area, we got to see some fiery-billed aracaris (Pteroglossus frantzii) in the distance.

 

 

While some others in our group got to see one close up, that was not my fate, but the next morning, the aracaris were in a little better light though still far away, allowing me to get a bit better photos.

 

   

We ended our second night at Talari Lodge with an owling outing – Steve managed to draw in a tropical screech owl (Megascops choliba) by playing its call on his phone. The owl who came had had an injury to one eye, with a pupil that would no longer dilate but s/he seemed to be flying fine and looked healthy. That bird gave us a nice long look at its beautiful self so that we retired for the night with a feeling of birding satisfaction!
