Costa Rican rambles 2 – exploring the fauna of the hotel botanical garden

My first close-up spotting of wildlife in Costa Rica was a butterfly familiar to me from North Carolina – a beautiful monarch (Danaus plexippus). Lots of little flies were buzzing about but they were a bit too quick for photos.

I wasn’t familiar with the first bird I saw, but after running into fellow traveler Dave, he kindly identified it for me as a white-winged dove (Zenaida asiatica).

 

  

Later and the next morning, I saw several wandering about the grounds and at the birdbath.

  

Another common dove was the white-tipped one (Leptotila verreauxi).

 

While roaming around, I ran into two more fellow travelers, Joy and Janet; together with Dave, we climbed a wonderful lookout tower placed in a strategic spot for birders. It looked down on a pond in one direction and a birdbath in another, where I saw the clay-colored thrush (Turdus grayi) – Costa Rica’s national bird, known locally as the yigüirro.  Its beautiful song is said to welcome the green rainy seasons and these birds were abundant in this garden and the other sites we would be visiting.

  

A couple species of hummingbirds appeared but I was only able to photograph the rufous-tailed hummer (Amazilia tzacatl).

  

While looking for it, I spotted what was to become one of my favorite Costa Rican birds, the rufous-naped wren (Campylorhynchus rufinuch).

  

I just fell in love with its brown speckled appearance and followed a pair flitting about the flower-laden bushes in the area.

 

Some “Northern migrants” put in appearances, including a Baltimore oriole (Icterus galbula) and some yellow-throated vireos (Vireo flavifrons).

   

 

Birds flitting in the treetops further included a few yellow warblers (Setophaga petechia) and Tennessee warblers (Leiothlypis peregrina), which I had not yet seen in the USA.

 

A beautiful blue-gray tanager (Thraupis episcopus) flew by and I saw my first male Cherrie’s tanager, for which I’ll post a better photo in a later blog. 

The high perch which we birders had offered me a first spotting of the variegated squirrel (Sciurus variegatoides), which lives up to its name with individuals showing very different coloring on their bodies.

  

I left the lookout tower to investigate more of the 10-acre garden and as it began raining, found a spectacular wasp or hornet nest. It looked quite different from varied perspectives, the underneath view making it look like a pair of pants hung from the tree by its legs.

 

 

 

 

 

The garden featured several man-made hives for stingless bees (Tetragonisca angustula); I didn’t see any buzzing about but perhaps they preferred to stay indoors during the rain.

Back near the lookout tower, I began hearing a pair of birds calling to one another with beautiful songs and notes. I was looking around for some small songbird but suddenly realized the concert was being offered by a pair of large melodious blackbirds (Dives dives), who really deserve their common name!

 

A somewhat more raucous set of cries alerted me to the arrival of a group of brown jays (Psilorhinus morio). They are much larger than the blue jays I see in my own garden and certainly seemed more social; they tend to move around in flocks. At first sight, they seemed a bit drab but a closer look shows they have a pretty muted appearance.

 

 

As I began following a hummingbird in an effort to get a close-up, Janet and Joy alerted me to a trio of Inca doves (Columbina inca) who were smushing together in a compact group for the night. It was almost dark and I had to adjust my camera settings a lot to be able to photograph them; they were becoming barely visible in the vegetation but oh so cute. Occasionally, one would leave the line and sit atop the other two but those below always got the third one to come down to the branch again.

Seeing some very cute rufous-collared sparrows (Zonotrichia capensis) foraging in the grass.

The next morning began with a spotting of a pair of masked tityras (Tityra semifasciata), who were difficult to photograph in the early dawn light.

A Hoffman’s woodpecker (Melanerpes hoffmannii, right) came by briefly and as the day started to brighten, a tropical kingbird (Tyrannus melancholicus) alighted on a branch.

  

It was after that sighting that I discovered a new bird (for me) – the social flycatcher (Myiozetetes similis); I had been calling all birds that looked like these great kiskadees – and they do look very similar to be sure!  And if readers see I have identified a bird incorrectly, please let me know!

  

My first evening and morning in Costa Rica taught me that the bird photography could be challenging; the lush vegetation meant that the birds are often in between dark leaves and shadows. This meant that I was shooting at high ISOs much of the time, with somewhat grainy photos as a result. I guess perhaps I should finally look into getting a photo editing program!

 

Winter wonderland – the bigger and colorful birds

In this second-to-last blog of the snowstorm series, I’d like to feature the bigger and colorful birds who demonstrated how they adapted their feeding habits to the prevailing weather. The Northern cardinals (Cardinalis cardinalis) actually didn’t change their behavior that much – they looked on the ground for fallen seeds and spent plenty of time at the feeders.

They spent some time in the snow-laden trees looking lovely, too.

  

  

The Eastern towhees (Pipilo erythrophthalmus) usually spend their time foraging underneath the feeders in search of fallen seed and they continued that behavior during the snowstorm. Unfortunately, the female was carrying a tick; I had already seen a robin and a junco with ticks on their faces – this may mean that the coming spring and summer will be an especially bad tick seasonal period for us.

 

The beautiful brown thrasher (Toxostoma rufum) looked both on the ground and at the feeders for his meals. Despite his size, s/he never bullied any other bird.

 

 

 

   

The remaining juniper berries on the red cedar trees (Juniperus virginiana) attracted the blue jays (Cyanocitta cristata).

The Northern mockingbird (Mimus polyglottos) was also seeking food there.

 

 

 

 

The cedar waxwings (Bombycilla cedrorum) and American robins (Turdus migratorius) had already been eating the juniper berries in the autumn; the waxwings had been by about a week earlier but now the robins were all over the trees, shaking off accumulated snow to get at the remaining fruit.

 

 

One robin looked as if s/he might have lost some outer feathers but it didn’t seem to affect her balance or flight. Occasionally, a robin also visited the meal worm feeder.

  

On the days following the big snowfall, as the snow melted more and more, the robins began eating it. During a previous snow event, they had joined the cedar waxwings on the roof of my house to get their drinks that way; now they were taking the snow from the trees.

They weren’t the only ones taking advantage of the opportunity. The Northern flicker (Colaptes auratus), who did not visit the feeder, spent a lot of time in an oak tree near the feeders eating snow.

 

  

There were a few birds that visit my yard who didn’t show up during the snow. They included the American crows and the hawks who often make the birds scatter from the feeders: the Cooper’s, sharp-shinned, red-tailed and red-shouldered hawks. They must have been looking for food elsewhere.

Some birds may have also avoided the feeders because of the large number of competitors who showed up, a feature of the next and last blog in this series.

Winter wonderland – the smaller and medium-sized birds

Oddly, during our January snowstorm, the brown-headed and white-breasted nuthatches did not visit my bird feeders – that was unexpected as they really do like the sunflower and other seeds, as well as the home-made suet. Other smaller birds did appear, however, and they filled up on the provided food since finding insects was almost impossible during those days.

The Carolina wrens (Thryothorus ludovicianus) were fans of the dried meal worms and at one point, I put out an extra tray of these treats on the dry front porch. Other birds are more reluctant to come onto the porch so they had a nice quiet feeding area, although they also spent time perched on the snowy bushes and feeders.

  

  

 

The Carolina chickadees (Poecile carolinensis) worked their way in between the other birds to reach the feeders, sometimes waiting patiently on a feeder pole for their turn.

The ruby-crowned kinglets (Regulus calendula), of which I have two visiting the feeders, were happy with the home-made suet. Occasionally, I smeared a bit of suet on dried flower stalks and they would perch there to snag a bite to eat. Other times, they just waited on a twig until the yellow-rumped warblers had vacated the area so they could eat in peace.

    

While the downy woodpecker (Picoides pubescens) is slightly larger, they are like the small birds in being somewhat hesitant to approach feeders if there is a crowd. Once on a feeder, they will feed and then hang on to take a look around.

  

The dark-eyed juncos (Junco hyemalis), who have an understated quiet beauty, were looking for meal worms.

    

The similarly colored tufted titmouse (Baeoloophus bicolor) often zoomed in on its target of the fruit and nut feeder without taking time to perch first.

The American goldfinches (Spinus tristis) didn’t come round very much, only snacking on some sunflower seeds. Since they often feed on the crepe myrtle tree seeds, they were likely finding enough food there.

The Eastern bluebirds (Sialia sialis) came in spurts of activity. They always look rather bedraggled when they get wet with snow or rain and perhaps prefer to stay drier under branches until there is a break in the falling moisture. Even wet, though, they are still attractive to me.

The smaller/medium bird group was rounded off by the house finches (Haemorhous mexicanus). The females were looking especially nice. The finches never have spats with anyone and are among the most peaceful feeder birds. Not everyone was like that, however, and the next blog looks at the rowdy ones.

 

 

Winter wonderland – sparrows and warblers

Yesterday, as I walked through my yard, I was surprised to see groups of daffodils sticking up their heads; it seemed rather early to me but last year we had early signs of spring as well. It is a big contrast to our weather conditions less than a month ago, though. On the 17th of January, our town was surprised by 11-12 inches of beautiful, powdery snow.

  

  

 

While our southern area often has a couple instances of (light) snow and/or an ice storm in the winter, our climate is generally fairly mild and temperatures in the 50s and 60s Farenheit are not uncommon during winter. So the brief but heavy snowfall was quite an event; our streets were empty of traffic as everyone stayed home and watched the falling flakes.

Some people built snowmen, others went sledding and walking, and some of us spent hours filling our bird feeders and watching the birds. I also made an attempt to photograph some frozen bubbles, which was very challenging since it was windy during the entire winter weather event.

  

The snow began slowly melting a bit the next day, which made some of the icicles on the house elongate to a length of almost 3-4 feet, but it wasn’t until Friday and Saturday that the snow and ice really started disappearing.

My yard looked beautiful, but I spent time on the 17th repeatedly knocking snow off the bird feeders and heated birth bath so that the birds could reach the food and water.

  

   

Although I saw a couple squirrels and the white-tailed deer (Odocoileus virginianus) also came by, I didn’t see other mammals like chipmunks, raccoons, opossums. But I had 25 different bird species come by on Wednesday and Thursday; on Friday and Saturday, two more species came by. I’d like to share some snow day photos of them all in this and the next few blogs.

First up are the sparrows and warblers. The chipping sparrows (Spizella passerina) usually get their seed from the hanging feeders in the front and back yards but now they were looking everywhere for a bite to eat. I had strewn some seed on the ground and they began looking there.

One found a trove of food and another came by asking to be fed, a request the first sparrow accommodated quite sweetly.

 

 

The white-throated sparrows (Zonotrichia albicollis) have an opposite feeding strategy, usually feeding on the ground and occasionally venturing up to a feeder. They, too, searched under the snow for some food.

 

The pine warblers (Setophaga pinus) tend to be rather shy; only very rarely does a pair visit together. Mostly, one shows up at a time; their beautiful yellow color was really highlighted against the white background.

 

The pine warblers did have to brave a bad-tempered bird to get to the feeders. One of the six resident yellow-rumped warblers (Setophaga coronata) has become very territorial, chasing away some other yellow-rumped warblers, the ruby-crowned kinglets and the pine warbler – in other words, the birds his size or smaller. He allows a couple other yellow-rumps to feed peacefully and I think perhaps they are his family members so that he tolerates them. He didn’t stop the other small birds from coming around, however, as we’ll see in the next blog.

 

My squirrel nemesis – a worthy opponent!

Today is Squirrel Appreciation Day in the USA, a holiday created by Christy Hargrove, a  wildlife rehabilitator affiliated with the Western North Carolina Nature Center. The Eastern gray squirrel species (Sciurus carolinensus) was first recorded in the Carolinas, so I thought I’d honor this wild creature by sharing some photos of the squirrels in my yard who sometimes drive me up the wall with frustration. There is one in particular who can get my ire up. Of course, I realize it may not always be the same creature – perhaps several of “my” squirrels are taking turns in trying to overcome my measures to keep them off my bird feeders. But I do think one in particular is especially tenacious and persistent.

The yard squirrels are lucky since my neighbor has beech trees and I have a couple oak trees that provide plenty of acorns; these mammals therefore have plenty of nuts to store for winter. I periodically see them digging little holes in the lawn and different parts of the garden, “squirreling away” the nuts they have found in the trees. I also saw one burying some grapes that I had put out for the birds; that didn’t seem like a good strategy to me, but I have since learned that they will make temporary caches so perhaps that squirrel was just hoarding a treat for later. They have also occasionally gone after the persimmons.

These squirrels aren’t satisfied with the natural bounty of the yard, however. They also want to get the nuts and seeds in my bird feeders, even when they have been able to  partake of the bounty strewn over the earth for the ground-feeding birds.

I learned early on that the bird feeder poles need to be at least 10 feet away from the roof of my house and any sturdy shrubs or stumps that they can use as a launching pad to bypass the baffles placed on poles to outwit them. They do go up the raccoon baffle from time to time, testing whether they now might find a way through it but so far that has not been a useful strategy for them. One has managed to climb a thick-stalked sunflower so that it could nip off the seed bud.

I had put a couple stumps in my front flower garden as natural decorations. Then, it appeared that one of the squirrels was using a stump as a launching pad – managing to land above the baffles atop the nut and fruit feeders.

    

I made the mistake of putting an oriole feeder on a pole without a baffle; I didn’t think it would attract the squirrels but apparently the jelly and nectar did appeal to one individual.

  

Another time I had only a hummingbird nectar feeder on one pole, which seemed rather flimsy. But the squirrel had to check it out all the same, even though there was nothing to its liking there.

As I have been removing invasive plants and shrubs from my yard, I’ve been adding native shrubs and plants. At one point, I thought it would be nice to have a black walnut (Juglans nigra) so I took a couple walnuts home from a park and then planted them in a deep plant pot with lots of soil over it. I had looked around beforehand and didn’t see a squirrel anywhere watching me, so I thought it was ok.

The next morning, I found a pile of walnut husks in the carport next to the plant pot. Then the next day, I saw one of the squirrels making off with the remaining walnut. Apparently, they can re-locate their hoarding caches partly by memory and partly by smell – so this squirrel must have discovered the tasty walnut by its odor (which I couldn’t detect at all).

 

  

   

The Eastern gray squirrels are only one of earth’s 200 squirrel species (there are four others in the USA: the fox squirrel, red squirrel, Northern and Southern flying squirrels and the ground squirrels, like this Uinta ground squirrel (Urocitellus armatus) seen in Yellowstone National Park.

 

I’m glad that I mostly only deal with one species and while I must admit that I don’t appreciate them every day, I always do admire their tenacity, perseverance and ingenuity in finding ways to overcome my strategies for outwitting them. The squirrels are not only a source of food for the neighborhood hawks, but also a source of entertainment for the humans.
