Arenal Area and Arenal Observatory Lodge
Overlooking the active Arenal Volcano the Arenal Observatory Lodge is an extraordinary location for birding and wildlife observation.
Located within the Arenal Conservation Area it offers the chance to explore a the Caribbean Slope's rainforest.
Its strategic location and elevation of 2,400 feet produces a combination of lowland and middle elevation species.
The clouds move through the area quite constantly producing intermittent rain showers pretty much any time of the year.
Cold fronts might produce rains that could last for a few days. Views of the Arenal Volcano can be as intermittent as the rain.
Birding around Arenal Observatory can produce a great variety of birds, just at the feeders you could watch Green Honeycreepers,
Shinning Honeycreepers, Crimson-collared Tanagers, Passerine's Tanager. On the forest edge as well as garden areas you could easily
find Hepatic Tanager, Orange-bellied Trogon, Black-crested Coquette, Green Thorntail, Violet-headed Hummingbird, Smoky-brown Woodpecker,
Golden-olive Woodpecker, Gray-headed Kite, White Hawk, Crested Guan, Great Curassow, Gray-headed Chachalacas, and tons of Montezuma Oropendolas.
The trails offering primary forest will produce species like Spotted Antbird, Dull-mantled Antbird, Bicolored Antbird, Nightingale Wren,
Plain-brown Woodcreeper, Streak-crowned Antvireo. Striped-breasted Wren, and Black-headed Nightingale-Thrush.
Arenal National Park
For birding purposes the best trail inside the park is located right before you enter the Arenal Observatory Lodge's property.
After crossing a stream to access the park you can explore a primary rainforest that could produce Spotted Antbird, Dusky Antbird,
Ocellated Antbird, Dull-mantled Antbird, Nightingale Wren, Black-striped Woodcreeper.
Gravel road from the main road to Arenal Observatory Lodge.
This gravel road is most of the time quite bumpy although in occasions it is smooth right after maintenance. I find this road quite entertaining, a
combination of open areas and later thickets and forest edge produce a great array of species. As you drive into this road you first find pastures with
scattered trees often producing White-collared Seedeater, Thick-billed Seed-Finch, White-throated Magpie Jay, Blue-Black Grassquit, Tropical Pewee.
Later as you drive along thickets and secondary forest edges you will encounter Barred Antshrike, Slaty Spinetail, Dusky Antbird, Great Antshrike,
Crimson-collared Tanager, Lineated Woodpecker, Bay Wren, Rufous-tailed Jacamar, Long-tailed Tyrant, Slaty-capped Flycatcher, and extremely difficult
to see but heard all the time in the brush Thicket Antpitta.
Arenal Lake Road
Another road worth checking is the one heading towards Arenal Lake. After the park station turn right and drive towards the lake's edge. If you are coming from Arenal Observatory Lodge just continue straight instead of turning right towards the park station. You could find this road quite entertaining with of Rufous-tailed Jacamar, Violaceous Trogon, Black-throated Wren, Broad-billed Motmot, Rufous Motmot and in occasions Keel-billed Motmot. Looking up in high branches you might be able to find a Great Potoo and White Hawks, Gray-headed Kites as well as other raptors can be seen around soaring or perching.
You will exit at the Arenal Lake Dam and need a 4x4 vehicle for this as some sections are quite rough for a regular vehicle.
The Hanging Bridges of Arenal
This 1.9 mile trail is quite spectacular however very busy, it offers a total of 14 bridges of which 6 are hanging bridges.
The forest here hosts a lot of wildlife, you will have chances to see Eye-lash Pit-Vipers, Howler Monkeys, Spider Monkeys, White-faced Monkeys.
Birding here can be interesting, mixed flocks contain Streak-crowned Antvireo, Slaty Antwren, Spotted Woodcreeper, Northern Barred-Woodcreeper,
White-fronted Nunbird, Scarlet-rumped Caciques. Other birds include Keel-billed Motmot, Rufous Motmot, Broad-billed Motmot, Purplish-backed Quail-Dove,
Dull-mantled Antbird, Spotted Antbird.. Right from the parking lot area you can usually see Short-tailed Hawk, White Hawk, Gray Hawk and in occasions Ornate Hawk-Eagle.
