Diario del proyecto Biodiversity of the Anacostia River

This week 293 observers made 1406 observations between Sunday, May 9, 2021 to Saturday, May 15, 2021. Among the top five observers, @dtread1 observed 100 examples of life in the Anacostia watershed; @stephen220 contributed 96; @ronwertz contributed 49; @epic2112 contributed 48; and @jmgconsult contributed 45. Rounding out the top 10, @jimdella contributed 35; @rdpost contributed 32; @kylehall1419 contributed 27; @treyncdc contributed 26; and @kewoodward and @rauvbbj each contributed 24. 139 people contributed one observation, 54 people contributed two observations, and 21 people contributed 3 observations. Plants stayed in first place (543 observations), followed by Birds (336 observations). Insects had 282 observations. Very shortly there will be many, many insect (cicada!) observations. Ray-finned fishes (Actinopterygii) had the fewest observations, with just one.

A few highlights of observations are provided below, to celebrate the wide variety of life found in the Anacostia watershed.

Kudos to everyone for a successful City Nature Challenge DC! The DC area did quite well overall, ranking third in observations, eighth in species, and second in observers out of 44 cities participating. Observations made from April 30 – May 3 were automatically included in the Anacostia Watershed as well. Here is a snapshot of the results for our area.

321 observers made 3326 observations between Friday, April 30, 2021 to Monday, May 3, 2021. Among the top five observers, @jmgconsult observed 344 examples of life in the Anacostia watershed; @ronwertz contributed 212; @dtread1 contributed 112; @onertwons contributed 109; and @carrieseltzer contributed 99. Rounding out the top contributors, @mitchgreene contributed 93; @lbyrley contributed 76; @jenwri and @mjmwx each contributed 66; and @dguerrero1999, @robpavlik, and @stella20009 each contributed 55.

Cicada-Palooza, Magicicadamageddon or whatever you want to call it, is off to a great start in the watershed. Both males and females of at least Magicicada septendecim are out and about, at least here in the Hyattsville and surrounding areas in PG County.

Remember that there are 3 species of Magicicada how to tell them apart? Find more info here: https://www.cicadamania.com/cicadas/where-will-17-13-year-periodical-cicadas-emerge-next/#species

But long story short: in order to make confident species ID you must take pictures of the abdomen and the presence/absence of orange coloring between the eye and the base of the wing.

This is also a great time to document interspecific interactions like predation and such. I saw/observed cicada nymphs, almost intact, in cat scat! Today I saw a House sparrow tackling a cicada while driving, could not make the observation...

Happy Cicada Watching!
