The garden for birds

A garden is always beautiful as far our aesthetic tastes are concerned but the users of Ocells del Jardins know that if it is full of birds the garden is much more interesting; that's why many of us set feeders and nest boxes or plant vegetation that we think can be attractive for birds, either as food, shelter, breeding place or other use.

It is interesting to know what plants are the most interesting ones for birds and a French study has drawn our attention in relation to a creeper of the genus Parthenocissus which produces a sort of berries that are eagerly consumed by garden birds. The author explains that the Black Redstart feasts on those berries extensively from October to February, in a fiery competence with the Blackcap, which often is a dominant species in feeders.

In the study, it was calculated that each Black Redstart ate between 50 and 100 berries a day when it was cold but would moderate their consumption when temperatures rose. This means around 20-40 g. a day per birds, that is, roughly the same body weight of the bird or more.

This plant is also widely used in gardening in Catalonia. In the Parc del Francolí of the city of Tarragona, we can find it in some pergolas where Black Redstarts, Blackcaps, Robins, Mediterranean Warblers, Stonechats, Blackbirds and Starlings share this food source, not without some quarreling.
