The announcement below is about the Cornell Lab of Ornithology's 24-hour birding marathon -- aka Big Day -- on May 13 and also a fund raiser for the the Cornell Lab of Ornithology. I thought you would want to know about it and that you might want to save the date.
Details about the day may be found here where you can also meet the Cornell team. If you scroll down you will find a link to bookmark if you want to follow the Cornell Team Sapsucker's progress. This year is international and includes two important Pacific Flyway regions: Monterey County and the Santiago Metropolitan Region, linked in the description.
You can also take a photographic walk down Big Day memory lane. So there is a lot of learn here.

There are two links here.
The first is a Photo Gallery. The gallery title is "Insects of Different Species Attack Each Other" by Meredith Root-Bernstein. The "brochure for the gallery, the study description, notes that "with a little patience, it is not difficult to observe flower-visiting insects (potential pollinators) attacking each other on flowers with varying degrees of aggression. However, this phenomenon has never been studied.....
The second links to the first scientific paper on this behavior which is completely accessible. It is a technical paper but you may want to learn more about the study. I point out two tables and a chart to peruse.
Table 1 includes the designations for the behaviors observed, their description and the behavior that resulted. Table 2 includes a list of the morphospecies observed (what it says it is but click the link for more details) - form and structure), family, and species examples. Further down there is a chart showing propensity to "aggressive behaviors."
The author's closing remarks provide a summary, possibilities for further research and a recommendation. "The observed interspecific (between species) dominance hierarchy in urban parks in Paris confirmed previous nonsystematic observations in a suburban garden on another continent with a substantially different and perhaps more biodiverse flower-visiting fauna (i.e., more beetles and butterflies). Further extending and refining the methodology to include finer morphospecies categories, more diverse habitats, weather conditions, species assemblages, and other parts of the world might reveal the factors influencing the formation and maintenance of interspecific dominance hierarchies by flower-visiting insects on flowers.
"The observation that the baseline behaviors are “neutral,” implying the least energy expenditure, along with the finding that sunshine and wind increase the rate of aggression, suggests that these aggressive behaviors could be partially explained by ethological accounts of arousal and stress. A fuller explanation that describes cost/benefit strategies of interspecific aggression among flower-visiting insects awaits elaboration. In addition, our observations suggest that the literature on interspecific aggressive interference should incorporate interspecies agonistic (conflict) hierarchies." (my italics)
A wonderful pairing. Don't forget to check the author's affiliations and positions, too.

Here is an animated video (9 m 42 s) from Bird Academy, Cornell Laboratory of Ornithology explaining the language of birds.
It is not only about how they sing but why.

A Hubble Space Telescope image of Rubin's Galaxy (UGC 2885) is featured in this Astronomy Picture of the Day (APOD) along with a brief explanation written by a professional astronomer. UGC refers to the Uppsala General Catalogue of Galaxies.
The explanation includes a link to the Annual Review of Astronomy and Astrophysics published An Interesting Voyage - Vera C. Rubin (49:1 - 28). Whether you know who she was or not, this essay is worth every word. The link was slow in loading so be patient if that is your experience.
Below is the abstract. I love the brief description of her decision to become an astronomer.
My life has been an interesting voyage. I became an astronomer because I could not imagine living on Earth and not trying to understand how the Universe works. My scientific career has revolved around observing the motions of stars within galaxies and the motions of galaxies within the Universe. In 1965, if you were very lucky and interested in using telescopes, you could walk into a research laboratory that was building instruments that reduced exposure times by a factor of 10 and end up making remarkable discoveries. Women generally required more luck and perseverance than men did. It helped to have supportive parents and a supportive husband.
And here is the Wiki entry about Dr. Rubin. It includes a note on "The Stuff Between the Stars: How Vera Rubin Discovered Most of the Universe." a children's book by Sandra Nickel and beautifully illustrated by Aimee Sicuro. The Amazon link allows a peek inside. The age range seems ambitious (age 6) and also seems appropriate for children older than the upper end (9).

California is "experiencing a rare 'superbloom',"write NPR's Joe Hernandez and Emily Bogle, "that's blanketing the ground with a variety of richly colored plants. The lush growth comes after a particularly wet past few months in California...."
Take a walk through the gallery of photographs, all oohs and ahs.
