To make hummingbird feed that is as close as possible to the nectar that the birds consume naturally, only use refined white sugar and water. Do not add anything else, especially not red dye, which can be harmful to hummingbirds.
This crafty upcycling project converts K-Cups into bubbling fountains that are magnetic to these charming creatures. You'll need a solar pump kit, a straw, a plastic shoebox, glue, scissors, skewers, and a soldering iron to put the project together.
A study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.
Individuals allergic to bee stings can safely consume honey because the venom produced by bees is not related to honey. The venom is injected through the stinger, while honey is produced from nectar.
This study started from a discussion with my co-author and postdoctoral researcher, Sabrina Rondeau, whose recent findings showed that these queens can survive submersion for over a week, which is extraordinary for a terrestrial insect. We wanted to understand how that's even possible.
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
A small, stingless bee may be able to raise coffee yields while fitting into real-world pest control programs, according to a new study from Brazil. In a field study on full-sun arabica farms, researchers reported a 67% higher fruit yield on coffee branches closer to colonies of the native stingless bee Scaptotrigona depilis, compared with branches farther away. The study was recently published in Frontiers in Bee Science.
For its fifth anniversary, 'Secrets of' turns its lens to one of Earth's smallest yet most vital heroes: bees. Far more than pollinators, bees are socially complex, fast-thinking individuals and the most important insects on our planet. Their impact on the natural world and humanity is immeasurable, and we're only just beginning to see how extraordinary they truly are.
If you spend a lot of time in the kitchen, you may find yourself needing to use a lot of disposable plastic products, from plastic bags to plastic wrap. While these tools can come in handy once in a while, a lot of sustainability- and health-conscious home cooks try to avoid them as much as possible. There are concerns that chemicals leached from plastic wrap could cause health issues, and being disposable and decidedly not biodegradable, many view these types of food storage tools as bad for the environment as well (and a great way to cut down on plastic waste in the kitchen).
The world spends 30 times more money destroying nature than protecting it. That's according to a new report from the United Nations Environment Programme (UNEP) that exposes a massive gulf between so-called "harmful investments" and financing that promotes nature preservation. The global environment agency's latest "State of Finance for Nature" (SNF) report is calling to phase out the US$7.3 trillion (6.2 trillion) in global investments that damage nature including into high-emissions energy infrastructure and manufacturing, for example.
When you think of farming, what ingredients do you generally associate with a successful harvest? The basics certainly come to mind: fertile soil, plenty of sunlight and lots of water. But there are other variables that can also mean the difference between a crop of healthy fruits and vegetables and a large heap of organic waste. And it turns out that one of those variables is a very small hawk.
Conservationists have now persuaded landowners to cut hedges in a more gentle rotation, with sections left uncut for up to three years, to enable more eggs to survive over winter. The caterpillars emerge with the foliage in spring and hatch into adult butterflies in July. The brown hairstreak is difficult to spot as a butterfly but every winter volunteers assess its populations by counting its minuscule cream-coloured eggs, which with careful searching are visible on the bare branches of blackthorn.
