🎨 Sortir du monde, de temps en temps, pour mieux respirer.

Le carnet botanique & entomologie de terrain, c'est l'idéal pour ça. On observe, on prend des notes, on dessine à l'arrache. 💚

Pyrenula ochraceoflavens

Yellow pox lichen

This crustose lichen has a yellow-orange, continuous or cracked thallus, and is usually more pigmented around the perithecial fruiting bodies. These perithecia have a weakly carbonized (blackened) pseudostromatic shell (the raised, blister like part around the ostiole). P. ochraceoflavens grows on the smooth bark of tropical forest trees, and has been recorded in Florida, USA, the Caribbean, and India. But there are so many variations within the genus and even within the species that delimitation is hazy at best. A pox on Pyrenula and all its related genera!

so, many of you have probably seen news about one of the first recorded severe case of HPAI (avian flu) in humans.

a lot of you who follow me are birders or inatters or adjacent. hence, a lot of you guys have birdfeeders.

from a rehab worker of almost 3 years: Disinfect your goddamn feeders. not only for HPAI but other diseases, such as avian pox, and for the safety of the birds

and of course, heres how!

now here at rehab we use rescue to disinfect, which is a big ol fancy thing that looks like this

for all our stuff. it's about 1-2tbsp rescue per 32oz water. however, most of you guys cant get a hold of it. so, heres some other things suggested by friends & coworkers that will work just as well

-diluted hydrogen peroxide

-bleach (diluted)

etc. in addition, it's best to use the hottest water you can handle in order to kill off more viruses (our industrial washer does up to 200°F, but whatever you can works just as well.)

the most important thing here is to USE GLOVES!!! PLEASE. pair of gloves to wash it and preferably when youre rinsing it use a DIFFERENT pair of gloves so it doesnt get dirty again.

lastly, if youre seeing visibly uninjured dead birds in your yard, lethargic birds at your feeder, red discolouration or growths on exposed skin, blood on your feeder, or anything else you might deem unusual, take down your feeder. the birds will get food elsewhere i promise, just leave it down for two weeks at least and sterilize it using any of the steps above.

also. please dont hand feed birds. yes even ducks. please please ignore what you see on instagram, it only creates more work for rehabbers. this includes trying to camouflage yourself and feed the birds from your hand when they dont know youre a person. it only hurts you and the birds, and yes this includes hummingbirds. do not try and feed birds off of yourself directly. please. thank you

be safe, clean your feeders, and happy birding!

in addition, below is an approximate of the procedure we use at my work to prevent outbreaks in our residents/patients.

changing aprons between birds, esp for personable birds (assimilated to people, like to fly onto you), switch gloves between birds, between touching hoses, etc. spray or dip + scrape shoes into rescue/accel solution before entering enclosures & or buildings. daily mopping w rescue solution, all dishes are hand washed with soap and hot water, then sent into an industrial washer @ 200°F.

Xylographa vitiligo

White-spotted woodscript lichen

You may have heard of vitiligo in reference to the autoimmune disorder that causes patches of skin to lose pigment, and you can see just by looking at this lichen why it was given the same name. X. vitiligo is a crustose lichen that has a mostly immersed thallus that is thin and pale, giving the wood it grows on distinctive pale gray or white spots. It produces farinose (mealy or powdery), blue-gray to green-brown soredia, and has round, oval, or slit-shaped apothecia with a pale-red-brown to black-brown disc. X. vitiligo colonizes dead conifer wood and stumps, fence posts, and driftwood in boreal regions of the Northern Hemisphere. It often grows alongside similar looking wood-script lichens, but can be identified using chemical spot tests on the soredia with KOH (+yellow) and PD (+ orange).
