Pretty handy.

"We present an unconventional sedimentary charcoal record preserved in a modern, post-bomb bat guano deposit and compare its accumulation to historical fire data. We find strong correlations between charcoal accumulation rates (CHAR) and non-winter prescribed burns... Our analyses show that charcoal preserved in bat guano is a reliable paleofire proxy system..."

Molecular Ecology

🤗🤗🤗 We welcome Maike Bonacker, Lisa Jung, and Eva Orpel as new members @Mol_Ecol @uniinnsbruck !

They do their master theses as a team in an #urban #ecology project in #Tyrol/Austria.

Using #BatDetectors and nets, they inventory the #bats of Innsbruck to analyse species composition as a function of the #hemeroby gradient, from forests to city center.

The Lesser Short-nosed Fruit Bats (Cynopterus brachyotis) are residents of the Sungei Buloh Wetland Reserve Centre. These are mothers with infants clinging on to them, with one curious youngster staring at the strange primate taking shots. 🙂 Taken on 26 May 2024.

I've seen these common bats in the neighbourhood, going for the fruits in the trees planted by residents.

On iNaturalist [ inaturalist.org/observations/2 ]

A dark brown bat with infant hanging from the rafters. The wings are dark with white wing bones. The fur on the back of the neck is brownish.
Same description as first image.

Here is the bat v. burrawong duel.

A brief explanation: when the bat colony is up-river, the bats routinely fly along the course of the river when leaving and returning. Unfortunately the local Currwongs are extremely territorial, particularly when they're nesting, and the bats sometimes fly too close (for a Currawong that means "within visual range"), and the Currawong proceeds to chase the bat off, screaming insults. In some cases it does more than pursue, it attacks, as seen in this example. Same caveats apply (low light, fast-moving subject, lousy photographer). For the faint-hearted, the bat survived.

Also from a different attack, the bat and currawong flying at street level, just as a pedestrian walks past a life-size plastic giraffe (I kid you not) and zebra in a front yard. Seeing is believing.

First of three photos showing a territorial currawong attacking a bat flying past, minding its own business. Here, the currawong is swooping up close behind the bat.
Second frame of the currawong attack. The bird has caught up to the bat, and has seized its trailing legs in its talons, while flaring its wings to slow itself and the bat. The bat is still flying, but not for long.
Third frame of currawong v. bat. The bird overflies the seized bat, still holding its hind leg in its talon, flipping the bat upside down underneath it. The bat can be seen shouting imprecations about the currawong's mother and lineage. In case you're worried, the bat escapes.
A different bat v. currawong chase. They're a bit hard to see, but this is a shot from a height of a footpath and houses. In shot are a currawong, a couple of meters above a bat, which is flying past a life-size plastic giraffe and baby zebra in a front yard. Walking past, oblivious, is a pedestrian next to a "BUS ZONE" sign. You couldn't make this up.

Ok, as threatened, here are some more #BatsOfMastodon #batstodon

Quality is variable, mostly tending to poor (low light, ISO noise, motion blur, all synonyms for amateur photographer).

However I can promise a few shots you've probably never seen before, one capturing IN ONE FRAME, ladies and gentlemen, a bat, a Currawong, a giraffe, a zebra, a human, and a Bus Zone sign.

Also the Bat v. Currawong aerial duel.

Plus some close encounters of the chiropteric kind.

I'll thread these up.

View from a third-story window showing a streetscape with the Brisbane river and dusk sky behind. Flying very close to the window, approaching at eye-level is a fruit-bat.
A sunset shot of the eastern sky over the Brisbane river. There are several cloud systems, some still pink from the western sunset, others dusky blue and grey from the gathering twilight. Just visible flying over the river is a flock of fruit bats, heading downriver for a night's foraging.
A single fruit-bat flying over Nightcliff bay and its bordering mangroves at dusk. The composition is really about the contrasting colors and textures of the peacefully rippled water and partially submerged green mangroves, the bat is a bonus.
A single fruit-bat flying over Nightcliff bay after sunset. The bat is silhouetted against the contrasting light and colour of the bay, which is dusky blue where the water is receding, and a shining gold where the flat sandy beach is exposed. A few shorebirds can be seen on the flat, while the foreground is made up of the barely distinguishable shapes of the shoreline mangroves.
