Gleanings of the Week Ending April 24, 2021

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Rising temperatures spark boom in Arctic lightning : Research Highlights – Lightning striking more than 10x as often as it did 10 years ago….the impact of climate change on the weather in the high north (particularly in Arctic Siberia).

This Bird Mimics an Entire Flock to Woo Females | Smart News | Smithsonian Magazine – The male superb lyrebird of Australia…imitates a mobbing flock (alarm calls warning of a predator in the area) to keep the female from leaving!

Top 25 birds of the week: April 2021! – Bird photographs….I enjoy them but also want to get outdoors and see birds!

Eating processed meat could increase dementia risk, researchers say -- ScienceDaily – A study with a large cohort (500,000 people) in the UK.

Photographer Travels Asia Capturing Beautiful Repeating Patterns – I liked the photographs for the repeating patterns but also how they capture the people and places. The photos capture the cultural landscape.

Stalking The Carnivorous Plants Of Big Thicket National Preserve – I can remember first reading about carnivorous plants in elementary school. I still find them fascinating.

How birds defend against brood parasites – I’ve already seen a pair of cowbirds at my feeder this spring; fortunately, they must have been migrating because I haven’t seen them again.

The Butterfly of Spring: Meet the Mourning Cloak – I haven’t seen one this spring…although I have in other years. All the ones I’ve seen in early spring are more battered that the one in the first picture!

Vitamin A for Nerve Cells – Another reason to eat those orange fruits and veggies. My favorites are carrots and butternut squash!

Washington’s Famed Tidal Basin and Cherry Trees Face Rising Waters – Planning initiated for how the area and its cherry trees could survive the rising waters in the coming decades. Some trees have already been lost.

Plum Blossoms

Our Thundercloud Plum is the first tree in our yard to bloom after the red maple. The flowers are shades of pink…the blossoms overwhelming the tiny red leaves initially. Later, after the flowers are gone, the leaves will be almost purple. Sometimes the March winds are strong enough to blow the flowers off the tree early.

The large brood of periodic cicadas are due again this year. 17 years ago – the last time the brood emerged – the plum was a young tree and we covered it with netting to protect it; the netting worked. Now is it big enough it should be able to survive the damage the cicadas will cause – which is good since it is too big to cover.

I did two high key images of the tree on a cloudy day….a little ‘art’ photography.

Back in April 2013 I posted about a butterfly in the tree. Now I recognize it as a Mourning Cloak – a butterfly that overwinters as an adult and needs plants like the plum for early spring nectar.

The plum tree is easy to appreciate in the springtime….and then the cherry tree next to it starts to bloom too….our front yard at its springtime best.
