I am missing:
1. Lithobates palustris (Pickerel Frog) - I have never seen this species and apparently it calls pretty early in the year. It also doesn't occur within 5-6 hours of where I live so I will need a rainy, early spring weekend. I don't know of any breeding locations in Texas however so it is going to have to require some searching and listening.
2. Anaxyrus houstonensis (Houston Toad) - The absence of this endangered species on my list is a combination of bad luck and not enough effort. It breeds in the relict pine forests within 100 miles of me, but most of the well-known and publicly accessible breeding sites were destroyed in a massive fire in 2011. There are still breeding populations, I just haven't been able to get up there and cross paths with them. I should be able to get this one.
There are a few species for which I have recordings from elsewhere, but I still need to record in the state of Texas:
1. Anaxyrus americanus (American Toad) - this species has a limited and poorly defined range within Texas. Furthermore its range is a long drive from me (7-8 hours) and it calls early in the year when I have less flexibility to drive up there.
2. Leptodactylus fragilis (Mexican White-lipped Frog) - this species is restricted to the Rio Grande Valley of southernmost Texas and only calls after periods of heavy rainfall. I have a few localities picked out, I just need some heavy rain to fall during a time period I am available to make the trip. A late summer tropical storm would be great, but it has been a few years since one hit south Texas.
3. Lithobates grylio (Pig Frog) - I have heard this species in Texas and have recordings from Florida. Unfortunately, the salt water storm surge from Hurricane Ike wiped out my known location for them before I could make a trip to get a recording. I am searching for a new location and hoping they make a comeback in the marshes that were inundated with saltwater.
There is one species I "kind of" have Texas recordings of. I have a recording of what might be Eleutherodactylus planirostris, but I am not sure and I didn't see the frog and it is calling from among dozens of E. cystignathoides. Their calls and their appearance are very similar!
My Woodhouse's Toad recording is terrible as well, so I need to make the effort to improve that one.
Here's what I have and what I'm missing. Can I finish them off in 2017? I don't know, but it gives me something to work towards.....Come on rain!

** - a recent evaluation of the Eleutherodactylus in Texas suggests that all the Eleutherodactylus in the rocky canyons of west and central Texas are E. marnockii and that E. guttilatus does not occur in the state. That means another one off the list!
*** - another recent revision of the "Cane Toads" has shown that the species west of the Andes and up into Central and North America is a separate species, the Giant Toad (Rhinella horribilis). I have chosen this taxonomy here, but also have a blog entry for the introduced Cane Toad (Rhinella marina) from its introduced range in Australia and elsewhere.
