Arbor Day
Arbor Day
The first Arbor Day in the US was held in 1872. Since then, the event has really taken root. On the last Friday of April, people across the country mark the occasion by planting trees, often dedicating them to a loved one. It"s also a great day to celebrate trees themselves. As well as providing homes for countless species of animals, trees absorb carbon dioxide and clean the air we breathe. They also help to keep cities cooler and can even play a role in preventing floods.Desktop Version
National Go Birding Day
National Go Birding Day
Get your binoculars and field guide and head to a local park, as it"s National Go Birding Day! Held on the last Saturday in April, this holiday celebrates birdwatching, an activity enjoyed by millions worldwide. There are approximately 18,000 known bird species around the world. Birds come in a wide range of sizes, colors, and behaviors, making them one of the most diverse groups of animals on Earth—from imposing eagles to today"s tiny snowy-winged star, a leucistic Anna"s hummingbird in the Australian Garden at the UC Santa Cruz Arboretum. These hummingbirds are typically vibrant in color, but leucism means some have decreased pigmentation, resulting in a paler appearance. Unlike albino birds, these hummingbirds do not have red or pink eyes. Their lighter plumage reduces protective camouflage, making them more vulnerable to predators such as hawks and feral cats.Desktop Version

The Sonoran Desert, Arizona
The Sonoran Desert, Arizona
Welcome to the Sonoran Desert, where life thrives despite the heat thanks to two seasons of rainfall. This subtropical desert spreads across parts of Mexico, California, and Arizona and is home to animals such as roadrunners, Gila monsters, and the Morafka"s desert tortoise. Its rainy seasons are followed by the blossoming of colorful wildflowers such as the brittlebush, seen in today"s image. These hardy shrubs are adapted to the dry seasons, with their silvery-gray leaves covered in fine hairs that help reduce water loss. Brittlebushes produce bright yellow flowers that bloom in clusters, adding splashes of color to the desert landscape. Another drought-loving desert flora is the saguaro cactus, which can live for over 150 years and grow up to 40 feet tall.

Vernazza, Cinque Terre, Liguria, Italy
Vernazza, Cinque Terre, Liguria, Italy
Perched on the rugged cliffs of the Italian Riviera, Vernazza is one of the five villages of the Cinque Terre area of northwestern Italy. Here, ancient buildings stand along the coastline of the Ligurian Sea, and life is filled with the hustle and bustle of the fishing industry. Vernazza got its name from the indigenous wine, "vernaccia," meaning "local" or "ours." One of the best-known monuments in the area is the medieval Doria Castle, built as a defensive fortress to protect the village from frequent pirate attacks. Thanks to the construction of the Genoa–La Spezia rail line in the 19th century, the village became more accessible by land. The car-free cobblestone streets are ideal for walking around. While here, you might want to visit the Chapel of Santa Marta and the Sanctuary of Madonna di Reggio. Vernazza is sometimes described as the pearl of the Cinque Terre with its natural port, colorful houses, and green terraces overlooking a sparkling sea.Desktop Version
