Rogitama

Whilst in Boyacá Department we paid a visit to the nature reserve of Rogitama, near to Arcabuco. This small private reserve of 29 hectares provides inspiration to those who would like to restore wildlife to Colombia. It is also a great place to see several species of rare hummingbird.

The reserve is at 2500m above sea level in the green valleys in the north of Boyacá. Roberto Chavarro and his family have been working since 1982 on the reforestation and restoration of a former cattle farm which had become eroded. Trees were planted to stabilize and protect the water sources. Hedges were established to increase habitat connectivity. They are improving the fertility and health of the soils using composting and worm farming.

As a result of this hard work there is now much more healthy undergrowth with moss, lichens and epiphytes in the trees which all store moisture and release it slowly which helps keep the streams running steadily. This means less erosive flash floods and fewer periods with a lack of water. Many species of insects are recolonizing the reserve.

They have also planted many flowering plants and bushes on the reserve which attract 19 different species of hummingbirds as well as flowerpiercers and other birds. Although it can get very cold at night, it is seldom below freezing and there are flowers year-round. With so much natural nectar, there is no need for artificial feeders.

Black Inca

Birders coming to Colombia from around the world are visiting the reserve to see a few harder to find species. Roberto is especially proud of the population of Black Inca (Coeligena prunellei) an endemic species classified as Vulnerable to extinction and only present in the Eastern Andes of Colombia. The population on the reserve seems to be healthy and they are easy to see. (They are also present in good numbers in the ProAves reserve Reinita Cielo Azul in Santander see my previous post).

Lazuline Sabrewing

Another rare species that is easy to see by the house is the Lazuline Sabrewing (Camplyopterus falcatus). I got this photo from the balcony just outside our room. They look much more blue in the right light!

It is possible to see other harder to find species including Golden-bellied Starfrontlet (Coeligena bonapartei), Mountain Velvetbreast (Lafresnaya lafresnayi) and Short-tailed Emerald (Chlorostilbon poortmani). You can get great opportunities as well to photograph commoner higher-altitude species like this Speckled Hummingbird (Adelomyia melanogenys) which sat just feet away.

But there is more ....Rogitama achieved some fame at the end of 2011 after several unidentified hummingbirds were photographed and filmed.  There is a picture here and you can see some youtube video here  and here. Apparently there are/were at least 3 individual birds and they come and go somewhat, so I didn't get a chance to see them.

Initially it was thought they might be Bogotá Sunangel (Heliangelus zusii) an enigmatic species only known from a 1909 skin marked "Bogotá" and never seen since. The rediscovery of this species would be sensational. Later, some theories emerged that this "Rogitama Sunangel" was a new species, a hybrid, or possibly a new sub-species or colour morph of the Long-tailed Sylph (Aglaiocercus kingi). DNA testing would resolve the debate. Feather samples were taken and sent to the University of the Andes in Bogotá to be tested. However, since then, no results have been released, so the mystery continues!

A Long-tailed Sylph from Santander. They like blackberry bushes!

Whatever the outcome it is fantastic that the hard work gone into restoring the habitat and encouraging the hummingbirds at Rogitama has been rewarded by the discovery of a very interesting bird as well as the presence of many others that are in decline elsewhere.

If you want to see hummingbirds in their more natural environment rather than at feeders, this is a great place to come.
