I think these are a Julia (above) and a Blue Morpho (below) butterflies.

A White-barred Piculet made a brief appearance before flying on.

The blackbird occupied second place and was observed in 84% of the gardens.

A way to say farewell to a story of a shepard’s journey to save his flock (and many other flocks) from a pack of wolves like none other.

An example of directional selection in action is provided by the story of an English population of coal tit [21] (see Figure 10).

In 2019, the blackbird was present in 85% of Luxembourg gardens and was therefore the most frequently found bird around the houses that year.

For the Great Tit (Parus major), Sparrow (Passer montanus) and Black Flycatcher (Ficedula Hypoleuca), the diameter of the hole will be 28 mm.

In 2018, the Great Tit was present in 85% of the gardens and as a result was the most frequent bird around houses that year.

Characterization and 454 pyrosequencing of Major Histocompatibility Complex class I genes in the great tit reveal complexity in a passerine system.

Coal tit, for example, cannot adapt eggs development in response to an increase in temperature occuring after laying (Visser et al. 2004).

The Great Tit may have 12 eggs in Europe, whereas the Oriental Parus species lay 3-7 eggs, and the African species 2-4 eggs.

With the help of my ring, I listen to birdcalls and learn what the nest of a blackcap, great tit or wagtail looks like – and why some eggs are speckled.

Just as common and familiar as the Great Tit, it is a little smaller, has a thin blue line instead of the broad black middle stripe of the latter and has the top of its head is blue.
