Guans on the Trails

One of the largest and most seen birds on my morning walks on the trails of Arenal Observatory Lodge was the Crested Guan, Penelope purpurascens (eBird link) for more info on this large turkey-sized Central American bird found from parts of Mexico to parts of northern South America and all over every Central American country. For more of my photos, see my Crested Guan Gallery. The male & female look alike and are difficult to differentiate with both being either all black or sometimes brownish. 🙂

Yes, you can see some of these at the Observatory feeder by the restaurant deck, but I prefer to find them in the wild and did on almost every one of the Arenal Observatory trails where all of these photos were made. Unlike the other large bird at Arenal, the Great Curassow, they fly a lot and spend as much time in trees as on the ground, foraging for food of fruit, berries, seeds, insects and small invertebrates. While the Curassow spends most of his time on the ground and doesn’t seem to be able to fly as well. I’ll try to do a post on the Curassow tomorrow since I’m a long way from finishing my Arenal ’24 Birds Gallery! 🙂 And I’m no longer doing blog posts a week ahead, but day by day! 🙂 Below this introductory photo is a gallery of 6 more Crested Guans I photographed in the rainforest on Arenal Observatory Trails.

Arenal Butterfly Gallery Complete

and with 3 new moth species for me and at least one new butterfly species. First, to see them all in the sub-gallery of my developing trip gallery, go to Arenal ’24 Butterflies & Moths Gallery with 15 species . . .

Click Image of 1st page of Gallery to see gallery.

Since I did a post on most of these from Arenal, I will let you look for the last minute photos in the gallery! 🙂 Though one is the featured image at top of post of a Hecale Longwing shot on my last morning there. And the birds gallery may take much longer with a lot more photos to sort through! And I think that I’m just getting slower at everything I do now. 🙂

Flowers at Arenal

Since I chose 30 different species of flowers to present, I decided not to put them all in this blog post, but start my 2024 Arenal Observatory Trip Gallery with the Flowers sub-gallery. Thus showing only two flowers in this blog post. The Featured Photo at the top is my favorite, an unidentified little wildflower that looks to me like a cute little purple-eyed forest creature! 🙂 And the shot below is not a first time flower for me, but finally I have a name for it, the Blue Ginger (with a Green Orchid Bee approaching it!) . . .

Now see all 30 cool rainforest flowers in this trip’s Flowers Gallery.

Giant Grasshopper Nymphs

Tropidacris cristata (linked to Wikipedia) is the scientific name of the Central & South American “Giant Grasshopper” or “Red-wing Grasshopper” and the plague we had at Arenal last week on a few plants was just their “nymphs” or babies! Interesting, colorful and amazing to see! See some of the giants in my Grasshopper Gallery. They are generally called “Lubber” Grasshoppers and these are just one of many species under lubbers. All grasshoppers together in Costa Rica number over 11,000 species. So it is difficult to get IDs of very many! 🙂 Here’s four photos including a close-up of these ‘nymphs” at work in Arenal.

More Butterflies, Last Morning

Saturday morning, both before and after breakfast, before leaving around noon, I got shots of the beautiful Hecale Longwing (Heliconius hecale) and a couple of moths with one quickly identified, using my Costa Rica Rainforest Moths book! 🙂 The other moth is unidentified, though I think he is in the Tiger Moth family. Here’s 2 shots of the Hecale and one of each moth . . .

Rainforest Butterflies

I only photographed 12 butterflies here this year and the photos of 3 are too bad a quality to share, but I will share the other 9 which are all but one repeats of species I’ve seen before, unless that unidentified one becomes a new species. 🙂 I did not go to the Butterfly Conservatory this year in nearby El Castillo-Arenal, or I would have more species photographed. And by the way, I consider it the best butterfly garden of the many all over Costa Rica, in case you are ever nearby. Here’s one shot for the email announcement, followed by a gallery of the 9 species . . .

Bird Eating from a Bird of Paradise

It is probably not unusual, but it was my first time to see a bird eating from a Bird of Paradise Flower, in this case a Rufous-tailed Hummingbird (linked to my Rufous-tailed Gallery). It was before breakfast this morning near the end of our birding hike as we walked through some of the lodge gardens on our way to the restaurant.

Nesting Time!

At least in this area, it is the time that most of the birds are nesting, meaning a different kind of bird activity. The feature shot at top is of a Yellow-throated Toucan coming out of her nest with a berry or seed in her beak. Below you can see a shot of how small the hole is that both the male and female squeeze through. I guess their beak determines the size of the whole, usually a remade or enlarged woodpecker hole. 🙂

And in the spirit of nesting season, there’s also a shot of an unidentified bird on her nest and a hummingbird nest. All this reproduction activity is an important part of the ecology of the rainforest that seems to be coming at the beginning of the rainy season.

The toucan nest hole seems to be just barely large enough for them to get their beaks through! 🙂

Barred Yellow

This is just my third time to see this unusual Yellow (among the many Yellows!). The Barred Yellow, Eurema daira (linked to my gallery) is found from Argentina north to the deep south of the U.S. It’s uniqueness is the brown, orange & yellow bars on the top of wings. The side view is similar to many Whites & Yellows. I’ve seen it twice here in Atenas and once at Arenal Observatory (where I’m headed tomorrow). See photos from other countries including the U.S. at butterfliesandmoths.

Tropical Checkered Skipper

This one I’ve seen multiple times in my garden but still love him: the Tropical Checkered Skipper, Burnsius oileus. You can see my other photos in my gallery or what others have submitted to butterfliesandmoths.
