More on Minnows

More on Gila Topminnows in Sabino Creek from Tom, Fred, and Bill.

Tom Skinner found the email with date and number info; specifically, 510 Gila Topminnow were released the morning of August 19, 2015.

Fred Heath wrote:

[On 5/17/2017] I found topminnows below bridge #1, above bridge #5 and below bridge #8. In addition, there were some below Anderson Dam where the water becomes shallow as it goes between some trees. In the deep pools just below Anderson Dam there were only chubs, including a few big enough to swallow many topminnows in a single gulp.

Today (5/22/2017) I’m still seeing a few below the Bear Bridge (these won’t last for many more days), below the Dam Bridge and below the dam itself in the next pool downstream from the large pool below the bedrock morteros.

And Fred notes: 

the picture from Bill Kaufman show[s] how the top minnows mouth faces upward [...] and helps explain why they are every bit as effective as the non-native mosquitofish in mosquito control (eating the floating larvae and pupae).

Thank you, Tom, Fred, and Bill for contributing to this fish story.

Marty scoped out buds on some of our canyon Night-blooming Cereus (Peniocereus greggii) on 5/18/2017 and caught the flowers on 5/21. Amazing!

Marty's Gila Topminnows

Marty writes:

Always a pleasure to cruise a bit with Fred! We got a 2nd observation of topminnows mixed with chubs at the Bear bridge.
Note the 2 light strips on dorsal surface of Topminnow females. Note black topminnow male.

Key Cn=Chub, TFn=Topminnow female, TMn=Topminnow male.

There's a new-ish fish in town!

Fish story and photos from Fred Heath

Today (5/10/2017) while searching for dragonflies and garter snakes from the Bear Bridge. I noticed some fish which were more guppy-shaped than our regular Gila Chub. As I was trying to figure out if it was just my imagination, a much smaller black fish came into view chasing my guppy-shaped fish. Having recently read an Arizona Game and Fish brochure on Gila Topminnows and Desert Pupfish, I knew I had found some of the Gila Topminnows which had been recently introduced into Sabino Creek (I believe up near Tram Stop #8….I will check with Josh). Like the guppies, the female topminnows are live bearing and so the females get quite large around the middle.

Unfortunately, the photos taken with my point and shoot camera are not the best quality and hopefully someone like Marty or Bill can get some better photos.[Anne notes: Marty's are tomorrow's post.]  However, they are good enough to ID the fish. 

The first photo shows a male (in his black breeding coloration) trying to accost a female. Along with the many females and a handful of very busy males, there were several young fish that I believe were also topminnows (see to the right and slightly above the male). 

The second photo shows another male eyeing a bunch of females just below the Dam Bridge. Note that sadly the fish in these two spots are in tiny ponds which probably won’t last until the Monsoon rains. 

In both places there were also Gila Chub and third photo has a small chub in the bottom right. They are generally longer and sleeker than the topminnows and its tail is forked where the topminnows have fan-like tails.

Stay tuned for more on this fish story!

New from Margarethe

Our favorite bug lady, Margarethe Brummermann, recently introduced her new poster: Butterflies of Arizona. As with the earlier releases, this poster comes with a numbered template and corresponding species list.

Margarethe writes:

After publishing my first 4 arthropod posters (see below), I have been asked for a butterfly poster more times than I can remember. But there is so much good stuff out on Butterflies ... I was a little intimidated. Now I think I have put together a collection that does justice to the unique diversity of Arizona and at the same time looks beautiful.
Many thanks to Ken Kertell, who allowed me to use a number of his excellent photos!
The size is 18 in by 24 in, it is printed on heavy, semigloss art paper with my giclee printer. That's really art print quality, not poster quality, and it will not fade. Cost: $25 plus shipping

If you are interested in any (or better, all) of these art quality posters for yourself or your favorite naturalist, please contact Margarethe via her comcast account (that's dot net) mbrummermann at  - you know the rest.

My Honey-Matt and I went hiking at Saguaro East on Easter (4/16/2017) and encountered this Antelope Jackrabbit, about 2 feet tall, who was kind enough to stay still for photos. The Jackrabbit is really a hare, of course, and the title "Osterhase" (German = Easter hare) seems fitting.

Fred's Find, too

Photos and story by Fred Heath, 4/17/2017

Fred writes:

The other day while walking along Sabino Creek on the east side just above the dam, I was surprised to find a Yellow Columbine (Aquilegia chrysantha). Although this can be a common flower up higher in the Catalina Mts. a little later in the season, I didn’t expect to find a plant in Sabino. I did check our annotated list and, sure enough, it was there, so someone has recorded it before. I’m fairly certain I’ve never come across this elegant flower in Sabino before.

Ned and I saw Yellow Columbine in this same spot in May 2013
