Eating so much seafood means drinking a lot of saltwater, but penguins have a way to remove it. The supraorbital gland, located just above their eye, filters salt from their bloodstream, which is then excreted through the bill—or by sneezing! But this doesn’t mean they chug seawater to quench their thirst: penguins drink meltwater from pools and streams and eat snow for their hydration fix. The fact that this farmer never tried to squeeze an ounce of publicity (or make a penny in profit) from his strange Valentines’ Day experience has lead many investigators to conclude that there would be no motivation for a prank on the part of Edwards. In further support of Edward’s claims is the uncanny trace evidence left behind in the field where the UFO had landed.

The most northerly penguins are Galapagos penguins ( Spheniscus mendiculus), which occasionally poke their heads north of the equator. The citizen science part of this comes in because there's just so much of Antarctica," Lynch said. "The way that we find penguin colonies is by and large through manual searching of imagery: image after image, foot by foot, scanning the coastline for evidence of penguin guano."

Over the past decade, BAS scientists have led investigations using satellite technology to identify, count and monitor different species in Antarctica and elsewhere. We have tested the capability of new satellites, applied bespoke methods to different species and developed automated counting techniques using Artificial Intelligence. These innovative developments have led to breakthroughs in the understanding of distribution and population trends, and increased uptake of the new technology by many other institutions and academics. It's that data that supports Lynch's Mapping Application for Penguin Populations and Projected Dynamics project. The main goal of the initiative is to provide Antarctic policymakers with more comprehensive data about penguin populations in one place. But the scientists need help locating all those birds, and for that, they enlist what they call penguin detectives. The first bird actually called a penguin was the now-extinct Great Auk found in the North Atlantic. Tragically, early explorers and their contemporaries found Great Auks a little too tasty, and the birds were all killed off. The great ( Diomedea) albatrosses are the largest flying birds on Earth and they live on remote, inaccessible islands around the Southern Ocean. These charismatic birds face a number of threats including incidental mortality (bycatch) from longline fishing, invasive species, disease and habitat destruction. Gentoo penguins “porpoise” by jumping out of the water. They can move faster through air than water, so will often porpoise to escape from a predator.

Most penguins swim underwater at around four to seven miles per hour (mph), but the fastest penguin—the gentoo ( Pygoscelis papua)—can reach top speeds of 22 mph! Dr Phil Trathan, Head of Conservation Biology at BAS, has been studying penguins for the last three decades. He says:
