Aruba

Burrowing Owls (local race) Athene cunicularia arubensis ©Caribiana Website

Aruba is a constituent island country within the Kingdom of the Netherlands, in the southern Caribbean Sea 29 kilometres (18 miles) north of the Venezuelan peninsula of Paraguaná and 80 kilometres (50 miles) northwest of Caribiana, CC BY-SA 4.0Curaçao. In 1986, Aruba became a constituent country within the Kingdom of the Netherlands and acquired the formal name the Country of Aruba. It has an area of just 179 km2 (69 square miles) and measures 32 kilometres (20 miles) in length from its northwestern to its southeastern end and is 10 kilometres (6 miles) across at its widest point. Aruba is geologically located in South-America, lying on the South-American continental shelf. Alongside Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. The Dutch Caribbean encompasses the ABC islands along with the other three substantial islands, the SSS islands. With a population of 108,000, Aruba is home to about one-third of the total population of the Dutch Caribbean. As one of the four countries in the Kingdom of the Netherlands, alongside the Netherlands, Curaçao, and Sint Maarten, Aruba shares Dutch nationality with its citizens.  Oranjestad is its capital.

Aruba has three distinct landscapes. The northwestern region is primarily characterised by flat batholith landscapes.

Notable landmarks include the conical Hooiberg Hill and rock formations like Ayo and Casibari. The northeastern part of the island features the oldest formations known as the Aruba Lava Formation. This region is marked by rolling hills, including Jamanota, and is home to Arikok National Park. Limestone terraces surround these two landscapes. The low-lying limestone terrace regions are defined by their white sandy beaches. The high plateaus on the north side of the island, in contrast, are constantly battered by the rough waters of the ocean, featuring caves and small natural bridge formations.

In contrast to much of the Caribbean, which experiences humid tropical climates, Aruba has a dry climate with an arid xeric landscape. Its relatively warm and sunny weather persists throughout the year with temperatures rarely outside of the range 27 °C to 30 °C. It averages just 20 inches of rain annually and, notably, remains dry even during its supposed rainy season (September to January). Rainfall can be highly variable, ranging from as little as 6 inches during strong El Niño years to over 39 inches in La Niña years. The arid landscape is not solely a product of its climate, but is also a consequence of extensive deforestation and exploitation during the Spanish colonisation of the island. Consequently, certain crops, such as aloe vera, thrive in this environment due to the high calcium-rich soil.

Birding Aruba

Aruba only has 2% of forest-covered land area and only 0.5% of protected natural area. The Aruba Conservation Foundation oversees the management of the conservation of 16 established protected areas, which encompass a total of nearly 25% of the island’s surface, as well as four Marine Protected Areas (MPAs) the Arikok National Park, established as formal conservation land in 2000, covers 20% of the island.   None of the forest was reported to be primary forest and no forest area was found within protected areas.

The geography includes naturally formed rooi or gullies that channel rainwater towards dams and ultimately the ocean. Other than Arikok National Park, the Bubali Bird Sanctuary is the only significant body of water on the island that holds the status of protected nature reserve and serves as a brackish water lagoon.

It has white sandy beaches on the western and southern coasts of the island, relatively sheltered from fierce ocean currents. This is where most tourist development has occurred. The northern and eastern coasts, lacking this protection, are considerably more battered by the sea and have been left largely untouched by humans. The hinterland of the island features some rolling hills. Being isolated from the main land of South America has helped the evolution of multiple endemic animals.

The island provides a habitat for the endemic Aruban Whiptail and Aruba Rattlesnake, as well as endemic subspecies of birds like Burrowing Owl and Brown-throated Parakeet. The flora of Aruba differs from the typical tropical island vegetation. Xeric scrublands are common, with various forms of cacti, thorny shrubs and evergreens. With the most known plant being the Aloe vera.

    …On a jeep ride through Arikok National Park, a hilly, rocky part of the island opposite the white-sand beaches, two crested caracaras perched as close to the gravel road as they could get (as if people-watching). We saw adorable, chatty bananaquits on the beautiful flowers at—of all places—our hotel. Even the troupials, large oriole-like birds, were everywhere.….
