Cullinen Park, 9/20/2025: Snowy Egrets forage by shuffling their feet, then stabbing at flushed prey. Spoonbills swish their bills sideways through the water, flushing and catching prey. This Spoonbill seemed to be catching prey flushed out by the Egret. 🦉 video: www.rickubis.com/rick/spoonbi...
Close view of a large puddle. The water is smooth. Centered in the picture are two large birds, wading from our right to the left. The water is "ankle deep" for the birds. (The large joint between the foot and the body is not a knee, but functions as an ankle.) The one in front covered with white feathers. It has a long neck, bent in a sharp "S" shape, a long sharp black beak with a yellow band from the base of the beak to around its eye. The legs are long and black. The leg near us is raised to show a bright yellow foot lifted above disturbed water. That bird is a Snowy Egret. Walking behind it is a larger bird. This bird is mostly pink on the wings and hindquarters, phasing into white at the front and the neck. The neck is also long and thin. The head has tilted so we can see it from the top. The beak is long, grey, and ends in a wide, spoonlike shape. The tip of it has dipped into the water. That bird is a Roseate Spoonbill. Both birds are foraging. The Egret shuffled its feet to flush prey. The Spoonbill swished its beak sideways to flush and grab prey. It seemed to be following the Egret on purpose. This is one of a series of images showing the Spoonbill definitely probing directly behind the Egret.

The Mexican honey wasp is a bit of an oddball: it makes and eats honey like a bee, but when it’s hankering for protein, instead of pollen, it eats other insects. A new study finds its gut microbiome is more like bees than wasps. Funded by USDA and NSF. journals.asm.org/doi/10.1128/...

Weee! A red-tailed hawk dives towards the camera. I love when they fold their wings to accelerate and form this beautiful shape. 🪶

Yesterday: I've had it with hearing the same story over and over again—another 100-year-plus rainfall event, another tragic result from people occupying the floodplain without an adequate warning system. More pain. More loss.
Floodplains Belong to the Rivers
From Houston to the Hill Country, we Texans keep doing the same thing over and over while expecting a different result.

For #FossilFriday, an ichnological 2-for-1 deal, with fossil scorpion tracks (L) & synapsid tracks (R) preserved from a Early Cretaceous (~130 mya) sand-dune surface: specimen displayed in the Mário Tolentino Museum of Science, São Carlos, Brazil; scale = 5 mm squares. 🧪🐾🦂 #ichnology
Two different types of 130-million-year-old fossil tracks from southern Brazil, preserved as impressions on a gray sandstone surface. On the left are smaller round impressions (3-5 millimeters wide) in alternating sets of 2 or 3 with a thin groove between them, made by a scorpion walking on the sand. To the right are larger (1.5-2 centimeters wide) in an alternating right-left pattern, which are tracks made by a synapsid that placed its same-side rear foot into the front-foot impression, known as direct register. A scale card to the left has alternating white-black squares that are 5 millimeters wide.

FINALLY, you can make an accurate size estimation lol!!
(But more importantly, I can stop using the ancient game's sprites to measure my characters when I talk to my team)

I finally saw it! A turtle ant mimicking crab spider actually attacking a turtle ant. This had been in presentations of mine for 7+ years now and I finally saw it!

5 years ago today, I took my first photo of comet Neowise. I had no idea what I was doing, but I had my mind set on capturing the best shot I could. I spent much of the rest of July 2020 practicing my shots, obtaining the right gear (within my tight budget), etc.

I am proud of my end result:
A photo of comet Neowise among a sea of stars. The comet is oriented vertically, with a wide white tail trailing off to the top right and the blue ion tail pointing toward the top left.
