Birding in Costa Rica - Part 11

15 January, 2025 

Natural Lodge Caño Negro - Entrada Los Chiles - Cinchona - Bougainvillea Hotel

     

     Caño Negro had delivered for us in fine fashion, but it was time to move on. Our time in Costa Rica was drawing to a close; there were still more birds to see, however!

     Before leaving the lodge we managed to spot a few familiar species. 

     A Black-striped Sparrow (Arremonops coniristris) was partially hidden, initially.....

      ..... but then popped up to please his human admirers!

     Blue-grey Tanager (Thraupis episcopus) was one of the most frequently seen species.

     Rufous-tailed Hummingbird (Amazilia tzacatl) was amazingly common, so as barely to garner a passing glance, but oh how thrilled we would be to see one today.

     Our stop at Entrada Los Chiles (El Parque) was very productive and we were greeted by a Cinnamon-bellied Saltator (Saltator grandis) feeding on fruit.

     A male Yellow-throated Euphonia (Euphonia hirundinacea) was no less shy to take advantage of the avian buffet.

     A female was conveniently on the ground nearby.

     A female Scarlet-rumped Tanager (Ramphocelus passerinii) gave us a pretty good dorsal view.

     And here is a more conventional view.

     
     A Buff-throated Saltator (Saltator maximus), like his Cinnamon-bellied cousin, was quick to claim a share of the fruit.

     A Clay-coloured Thrush (Turdus grayi) is the national bird of Costa Rica, after all, and deserves its place in the sun.

     It reminds me of some people I know, not flashy, but always reliable.

     Who could fail to be enchanted by a Black-cheeked Woodpecker (Melanerpes pucherani)?

     Baltimore Oriole (Icterus galbula) always reminded us of home; indeed, it will not be long before they start to show up at our backyard feeders.

     We have grape jelly and oranges ready for their arrival. No one goes hungry!

     A Red-legged Honeycreeper (Cyanerpes cyaneus) is a sensational little bird.

     Here it is sharing a banana with a Blue-grey Tanager.

     We moved on, and from time to time had to share the road.

     A Groove-billed Ani (Crotophaga sulcirostris) paid little heed to the cattle, no doubt concentrating more on the grasshoppers and other insects stirred up by pounding hooves.

     We were in an area of grassland, very much to the liking of various seed eaters, and we were not disappointed with good numbers of individuals and species.

     The bill of a Nicaraguan Seed-finch (Sporophila nuttingi) is really quite arresting.

     A White Peacock (Anartia jatrophae) was a pleasing addition to our morning.

     A female Variable Seedeater (Sporophila corvina) was present too.

     Grey-breasted Martins (Progne chalybea) were like laser-guided missiles picking off aerial insects, but  two birds perched on a wire for a few seconds.

     Thick-billed Seed Finch (Sporophila funerea) added to the very agreeable challenge of identifying grassland species.

     There is no confusion about a Greater Kiskadee (Pitangus sulphuratus).

     Red-headed Paper Wasp (Polistes erythrocephalus) is apparently common to abundant in Costa Rica, but we did not see them often. 

     This is an insect that it best left alone to go about its business; its sting rates 3/5 (intense) on the Schmidt Pain Index.

     In addition to grassy fields, we were in an area of flooded land, creating perfect habitat for wetland species.

    The number of juvenile Northern Jacanas (Jacana spinosa) was astonishing.

     As might be expected herons were very much in evidence.

Bare-throated Tiger Heron (Tigrisoma mexicanum)

Tricoloured Heron (Egretta tricolor)

     The highlight from this stop was, without a doubt, clear looks at a White-throated Crake (Laterallus albigularis).

     This is a tiny bird (14-16cm), normally staying within cover and difficult to see. We were fortunate to see it so well and it was a "lifer" for most people.

     Our attention was so rivetted on the Crested Caracara (Caracara plancus) seen below that we didn't notice the Wilson's Snipe (Gallinago delicata) at the time and only became aware of it when editing the picture.

     Domestic horses came for a drink.

     A Zebu bull is an impressive animal.

     I am struck by the confiding nature of American Kestrel (Falco sparverius) in Cuba and Costa Rica, in sharp contrast to the skittish nature of this species at home.

     We stopped along the road to look at a Brown-throated Three-toed Sloth (Bradypus variegatus), a curious mammal, and the object of everyone's delight.

     In addition to the algae in their fur, clearly visible above, B. variegatus lives commensally with sloth moths, including Cryptoses choloepi, which live in the sloth's fur and lay eggs in the dung.

     I know that Victoria and Carlos disagreed as to the life cycle of the moth, but I believe that Victoria expressed the process as herein described so it appears that this is vindication for her.

     To support this conclusion I consulted the following, all of which support the life cycle of sloth moths as enunciated above, beginning with eggs laid in dung.

     It started to rain and we clambered quickly onto the bus to head off to Soda Cinchona where we would have lunch and (surprise!) look at more birds.

     I was glad not to be the driver under these conditions.

     Upon arrival we were greeted almost instantly by several Blue-throated Toucanets (Aulacorhynchus prasinus caeruleogularis), the equivalent of a royal welcome for us.

      Conditions for birding were far from ideal, but we did the best we could.

     After all, we can't change the weather, nor can we blame anyone for it.

     The waterfall looked quite splendid through the mist.

      A Crimson-collared Tanager (Ramphocelus sanguinolentus) shared a banana with a Silver-throated Tanager.

         Indulge me while I add another picture of a Blue-throated Toucanet.

     The rain did little to deter hungry birds, anxious to gobble up their share of the smorgasbord laid out for them.

     Stoicism was the order of the day for a Baltimore Oriole.

     A Blue-grey Tanager was handsome, as always, basking in its cerulean splendour.

     It was exciting to share the day with a couple of Green-crowned Brilliants (Heliodoxa jacula).

     Here is a very poor picture of a Violet Sabrewing (Campylopterus hemileucurus).

     Reliable as ever, a Rufous-tailed Hummingbird joined the party too.

     When it was time to leave the sun was doing its best to poke through the gloom and a rainbow was our reward.

     How would you like to be a lineman working on this tangle?

     By late afternoon we reached the Bougainvillea Hotel, that oasis of splendid calm in a troubled world.

     And yet another rainbow greeted us.

     It was time to go for dinner.
