The canarian common kestrel (Falco Tinnunculus) is a small falcon abundant in Gran Canaria. Its name in Spanish is "Cernícalo". It is the most extended bird of prey specie in the canary islands. Its size is 30-35 cm from head to tail and 70-80 cm wingspan.  As a specie, It is native of the Canary Island but not endemic. There are 2 subspecies: Dacotiae in Lanzarote and Fuerteventura and Canariensis in the rest of islands. Its diet mainly consists of smaller birds, small mammals like mice (introduced in the canary islands). In Gran Canaria, the canarian common kestrel also hunts the endemic Gran Canarian giant lizard (Gallotia Stehlini). Those living near the urban centers also hunt caged birds like parakeets. A gorge situated near Telde has been named after this bird. This is the "Barranco de los Cernícalos". This is an advisable place for a trekking tour because ot the abundant vegetation of the gorge.

When the moon let itself be loved

A half moon is nice to be observed through a powerful telescope. The raking light casts shadows of the moon's relief. When the sky is very clear and windless, using our 16 inches telescopes we still enjoy sharp images despite of magnifying 225 times! One of our guest participating in our workshop last Wednesday put his mobile phone on the eyepiece and we took this nice picture of our natural satellite. Enjoy, and share.  Thanks.
