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.
