Biodiversity<br />
É às primeir<strong>as</strong> hor<strong>as</strong> do dia que o tordo<br />
anima a <strong>Quinta</strong> com o seu canto.<br />
The song thrush livens up the <strong>Quinta</strong> at <strong>da</strong>ybreak.<br />
As árvores e <strong>as</strong> aves <strong>da</strong> <strong>Quinta</strong><br />
É a diversi<strong>da</strong><strong>de</strong> <strong>de</strong> espécies vegetais presente<br />
na <strong>Quinta</strong> <strong>de</strong> <strong>São</strong> <strong>Francisco</strong> que faz <strong>de</strong>la um<br />
local <strong>de</strong> eleição para vári<strong>as</strong> aves. A isto junta-se<br />
a pequena dimensão <strong>da</strong> proprie<strong>da</strong><strong>de</strong>, que lhe<br />
granjeia visit<strong>as</strong> d<strong>as</strong> espécies que habitam nos<br />
terrenos vizinhos.<br />
Mesmo num espaço limitado, são fáceis <strong>de</strong><br />
i<strong>de</strong>ntificar algum<strong>as</strong> preferênci<strong>as</strong> no território.<br />
Se espécies mais urban<strong>as</strong> como a andorinha<br />
e o par<strong>da</strong>l são sobretudo observáveis perto do<br />
núcleo <strong>de</strong> edifícios, junto à entra<strong>da</strong>, outr<strong>as</strong>,<br />
como o pica-pau malhado são difíceis <strong>de</strong><br />
encontrar: muito sensíveis à presença humana<br />
preferem retirar-se para os limites <strong>da</strong><br />
proprie<strong>da</strong><strong>de</strong>, sobretudo em zon<strong>as</strong> n<strong>as</strong> quais<br />
predomine o eucalipto.<br />
Indiferentes à espécie <strong>de</strong> árvore que os acolhe,<br />
rol<strong>as</strong>, pombos e estorninhos, escolhem<br />
sobretudo exemplares <strong>de</strong> gran<strong>de</strong> porte. Rapin<strong>as</strong><br />
e cucos — os últimos visitam a <strong>Quinta</strong> apen<strong>as</strong><br />
no Verão — escolhem <strong>as</strong> árvores com troncos<br />
livres <strong>de</strong> ramagem, por serem os melhores<br />
para pousar.<br />
Outros animais, como a alvéola-cinzenta, são<br />
observáveis ao longo <strong>de</strong> todo o curso <strong>de</strong> água.<br />
E <strong>de</strong>pois há o pisco-<strong>de</strong>-peito-ruivo ou o melro,<br />
que surgem um pouco por todo o lado.<br />
Na ver<strong>da</strong><strong>de</strong>, mesmo sem uma relação directa<br />
entre uma árvore e uma <strong>de</strong>termina<strong>da</strong> espécie <strong>de</strong><br />
ave, a varie<strong>da</strong><strong>de</strong> <strong>de</strong> aves presente na <strong>Quinta</strong>,<br />
confirma que a diversi<strong>da</strong><strong>de</strong> <strong>de</strong> flora ali existente<br />
é um dos <strong>as</strong>pectos que a torna única.<br />
The trees and the birds in the <strong>Quinta</strong><br />
The re<strong>as</strong>on why various bird species have chosen<br />
<strong>Quinta</strong> <strong>de</strong> <strong>São</strong> <strong>Francisco</strong> <strong>as</strong> their home is because<br />
of the diverse existing vegetation. Ad<strong>de</strong>d to this is<br />
the small size of the property, which attracts the<br />
visits of species from the surrounding grounds.<br />
Even if the area is limited, it is e<strong>as</strong>y to i<strong>de</strong>ntify<br />
some territorial preferences. If more urban<br />
species, like the swallow and the sparrow, can be<br />
mainly seen closer to the group of buildings next<br />
to the entrance, others like the greater spotted<br />
woodpecker are difficult to find; very sensitive to<br />
human presence, they would rather retreat to the<br />
property’s boun<strong>da</strong>ries, to are<strong>as</strong> where there are<br />
more eucalyptus.<br />
Indifferent to the species of hosting trees, doves,<br />
pigeons and starlings normally choose large-<br />
sized trees. As for the birds of prey and cuckoos,<br />
the latter only visit the <strong>Quinta</strong> in the summer,<br />
they choose branch-free tree trunks, <strong>as</strong> they<br />
are the best on which to perch.<br />
Other animals, like the grey wagtail, can be seen<br />
along the extension of the water course. And then<br />
there is the robin or the blackbird which can be<br />
seen all over the property. In fact, even if there is<br />
no direct relationship with a tree and a respective<br />
bird species, the existing variety of birds confirms<br />
that the flora diversity is one of the features that<br />
make it unique.
