David A. Landes Discusses various wildlife of the American Midwest and other related topics. Here I wish to showcase several of my scientific publications. A., J. H. Hunt, and A.

I also wish to share my devout enthusiasm for the preservation of our native species (and have this serve as a mini bulletin on native wildlife of the Midwest region). Other topics connected with our regional natural heritage are included. Publications:

We are seeking public comments on potential regulation changes regarding paddlefish through Nov. 14.

Paddlefish are unique members of Missouri sportfish and commercial fisheries. Named for their large, paddle-shaped snouts, these fish can grow to seven feet and weigh more than 100 pounds!

Love is in the air!

A pair of meadowhawk dragonflies forms the classic "mating wheel" as they fly through a clear blue sky. These aerial predators help keep mosquito populations in check, making them some of nature's most beneficial insects.

Angel is back!! She is the rarest wild bird living year round in the state of Nebraska.

Angel is NOT an albino. Albinos have pink eyes and all white feathers. Angel has dark eyes, and a mostly red tail. You can see a bit of red behind the cedar branch.

Angel is a leucistic Red-tailed Hawk. Leucism is a rare gene that causes lack of pigmentation in the feathers making them appear white.

As she aged, Angel has became almost all white. Her wings look like "angel wings" when she soars overhead. Hence the nickname, Angel.

Actually, Angel never left. She has lived along the same part of the river for over a decade. During nesting season she becomes a "ghost" and disappears for months.

I haven't seen her since Feb. I have made a dozen trips looking for her. We are always concerned that something has happened and she won't return.

Then on the 13th trip this week she suddenly appeared on the top of cedar tree as if to say: "Here I am Ole Photog, catch me if you can!"

Angel is not kind to Photogs! She takes flight faster than any Red-tail I've seen. That is probably why she has survived so long through all the Nebraska winters.

I only got one "butt shot" of her taking off this time. My dream shot is her banking with red tail fanned. Now that we have met again ... "I'll be back".

Stay tuned. If you want to see her red tail, I'll be posting a take off shot tomorrow.

By consuming plants and then being eaten themselves, caterpillars transfer more nutrients and energy to animals than any other group of insects.🤔
Just think about it…

GIMLI will probe the Marius Hills Pit for a hidden lava tube that could shelter astronauts and reveal the Moon's volcanic past.

I realize this is out of season, but I love these pics
