THE BENEFITS OF INSECTIVOROUS BIRDS
The insectivorous birds, whose task in the forest balance, as regulators of plagues is well known. It has been one of the most studied entomophagous animal groups. Some of these birds, like the Woodpeckers build nests with their powerful beaks; Tits, Chickadees, Nuthatches, Redstarts and Old World flycatchers are troglodytes. This means that they use natural gaps found in trees and thick branches to nest and protect themselves from bad weather or predators.
The importance of these birds is clearly reflected, by studying the stomachs of Bluebirds in which large quantities of Tortrix viridiana or Catocala sp. were found, amongst others. Also, Thaumetopoea pityocampa caterpillars (Pine processionary) in their first stages, are very common in insectivores studied from autumn to winter. It has been estimated that the number of insects eaten by a couple of these birds in one year can be up to 5 kg.
These results show the usefulness of these birds in maintaining the biological balance in forests, which justifies the placement of artificial nests in forests. The nests successfully replace the lack of natural holes in trees, achieving a generalised increase in cave-dwelling, insectivorous bird populations. Also, their stability and presence in the forest ecosystem with the resulting benefit that this represents in the fight against harmful insects.
USING THE BIRDS’ NESTS
The nests are used during campaigns to protect insectivorous birds, by increasing their populations through the installation of nests.
The use of nests is very generalised amongst Conservationist Societies, Ecological Groups, Universities, Vocational Schools, Town Halls, Education Centres, Summer Camps, Nature Classrooms, Youth Associations and in general anyone who is interested.
PLACING THE BIRDS’ NESTS
There are no fixed rules on the most appropriate position the entrance hole to the nest has to have, given that it depends on a specific location. The East and South orientations are most common. Orientations frequently exposed to very strong winds, storms or any other unfavourable atmospheric conditions should be avoided.
In order to prevent slipping, it is advisable to install them in-between the secondary twigs of a branch or in the crotch of a tree. The height location seems to be irrelevant regarding the birds nesting. Although to avoid being handled by the inquisitive, in public places it is recommended that the nest be installed a minimum of 4 - 5 metres from the ground.
The right time to install the nests is in late autumn, so that the birds can use them for shelter during the winter period. Once they have been familiarised with their presence in the forest, they will be easily accepted for nesting next spring.
