Flamingos are very social birds; they live in colonies whose population can number in the thousands. These large colonies are believed to serve three purposes for the flamingos: avoiding predators, maximizing food intake, and using scarcely suitable nesting sites more efficiently. Nevertheless it is not difficult to see two of them fight to contend a partner or some food, and it is precisely on these occasions that they "swell" to look bigger!

Ría Celestún, Yucatán, Mexico | November 14, 2018
Flamingos filter-feed on brine shrimp and blue-green algae as well as larva, small insects, mollusks and crustaceans making them omnivores. Their bills are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae, which line the mandibles, and the large, rough-surfaced tongue.

Río Lagartos, Mexico | November 11, 2018
Rio Lagartos is a nature reserve in northern Yucatan. The name comes from the Spanish colonizers, mistaken both of the words Rio and Lagartos: in fact it is a huge estuary (ría in Spanish), not a river (rio), and the "lizards" that live there are not alligators (lagartos), but crocodiles.
The Mexican crocodile (Crocodylus moreletii) is distinguished from alligators by teeth. In fact, it has a perfectly aligned teeth. The fourth tooth on the lower jaw is visible when the mouth is closed because it is slightly larger than the rest of its teeth.

Sud Sardegna | December 07, 2017
Every tree is important, whether it be one among many others in the wood, alone in a meadow,
in an urban park, along an avenue, or in an orchard...
Every tree is essential for the life of the planet, and it is also a world in itself, where animals of
all kinds live, find their shelter, feed themselves and reproduce.

According to the mythological narration, Apollo sent a white raven, or crow in some versions to spy on his lover, Coronis. When the raven brought back the news that Coronis has been unfaithful to him, Apollo scorched the raven in his fury, turning the animal's feathers black. That's why all ravens are black today.
