Google is wishing everyone a happy Earth Day this year with six animated Doodles.
For Google's annual salute to Earth Day in 2014, the company has incorporated a series of six animals – the Rufous hummingbird, dung beetle, moon jellyfish, Japanese macaque, puffer fish, and veiled chameleon – into various animated logos:
Keep clicking on the logos to cycle through them all. You can also share the logos on Google+, Facebook, or Twitter, or do a Google search for more information on all of the animals.
The hummingbird logo may perhaps be a bit of an "hat tip" to those who regularly follow Google search news. In September, Google revealed Hummingbird, an overhaul of its core search technology that aimed to answer more complex queries.
One of the more comical animated logos is the one featuring a dung beetle, where the second O in the Google logo is – you guessed it – a piece of dung.
Google is also teaming up with Time magazine to celebrate Earth Day, asking users to share their favorite photos on Google+ with the #MyBeautifulEarth hashtag, and Time will be sharing them on their website. You can also view all the entries here.
The theme of this year's Earth Day is "Green Cities," with the goal of rebuilding cities and towns to be more sustainable. First celebrated in 1970, Earth Day is observed every April 22 in more than 190 countries to raise awareness about environmental issues.
Google has a long history of Earth Day doodles, starting back in 2001. The interactive 2013 Earth Day logo let you control the weather, while the 2012 Doodle featured an animation of flowers blooming, and an animal-themed Doodle in 2011 featured a panda, penguin, and other cute creatures.
