Dear Shrew-Fessionals and Shrew-Mateurs,
It has been quite a long time since I sent out the last issue of ST and quite a bulk of mail has accumulated, so this issue is a bit lengthy. Please accept my apologies for the delay in posting your messages. I would like to thank everybody who has contributed by sending in enquiries, photos and reprints of papers or by simply joining the group. If you cannot find your posting in this issue, be ascertained that it will be in ST 2/9, which will also include information on insecticide effects, ectoparasite collection and bibliography additions.

This is a plastic trap that a friend of mine has used for the last couple of years that is probably better for live-trapping shrews than a sherman- much more sensitive plus the plastic reduces mortality due to cold (if that's a concern). I believe that it should also be cheaper than a sherman in Europe. I recently ordered 100 for myself specifically for shrews.

1b) Ugglan Special I
Date: Fri, 20 Mar 1998 20:00:23 -0800 (PST)
From: John D Boone <boone@med.unr.edu>
I am NOT a fan a Sherman traps for many reasons. They are hard to clean, the mechanism is finicky and located in the worst possible spot, ie on the floor of the trap where the trap rodent urine, feces, and bait. They have terrible ventilation and moisture easily condenses inside the traps
A small company in Sweden makes mesh traps that I find far superior, in addition to being cheaper (even including the overseas shipping). Unlike Shermans, the trap mechanism is not spring loaded, but gravity controlled; it is elevated above the floor of the traps so does not get fouled with mouse droppings. They do not subject the trapped animals to the hi and low temperature and humidity extremes of shermans; they have a lightweight, integrated sun and rain cover; they will capture multiple animals and are not subject to accidental setting off. They come in various sizes suitable to a large range of small mammals. By the way, I have absolutely no financial stake in any traps, so this is not a monetarily motivated endorsement.

1c) Ugglan Special II
From: "Heikki Henttonen" <heikki.henttonen@metla.fi>
Organization: Mets{ntutkimuslaitos

The best live trap for almost all purposes in the Swedish "Ugglan" live trap. It is much cheaper than e.g. Shermans. The Ugglan trap in itself has not tight roof (sides and "roof" are wire mesh), but the trap has a separate cover, easy to put on the trap and which allows for ventilation though sides. Yes, these traps catch more than one animal which is a great advantage in vole research, but, I admit, may be a problem in shrew research. The partial solution is a frequent checking of traps, which in its turn limits the number of traps that can be used simultaneouly. It is possbile to add bedding and also food into the trap. However, bedding easily blocks the trappig mechanism after the animal is in the trap, which in the case of shrews would, in fact, be an advantage. For vole research I certainly recommend Ugglan. Recently I discussed with some Americans who had used Ugglans and Shermans at the same time in their rodent trappings and they all clearly preferred Ugglans. The survival of voles is better in Ugglans than in Shermans, especially when the weather is warm or hot. However, if the primary goal is to live trap shrews, then advantages may be more in balance, but if adding bedding could prevent multiple captures of shrews, then I would take Ugglans. The model with a narrow and light treadle catches Sorex minutus. I have no experience of Crocidura. Personally I have used Shermans in USA, and I prefer Ugglan, not to mention the price difference. In your situation I would first order a smaller number of Ugglans and test them with bedding and food for shrews. In my vole research I have never used bedding.
Best regards, Heikki Henttonen
1d) Ugglan Special III
From: W. Haberl - shrewbib@sorex.vienna.at
Thank you all for your advice regarding traps. I have ordered and purchased the recommended Ugglan traps (100 pcs). The mechanism is simple and similar to that I have used in constructing the traps I have used for my own studies some years ago (without knowing). Indeed, the trap is cheaper than others and it is fit for multiple catches. The only drawbacks I can see so far are that it is a bit bulky (which means quite a heavy load when having to set up 100 traps) and that the galvanized steel tends to rust at the joints, but this does not affect the mechanism. Apart from that it seems to be a neat trap. I will report to the group as soon as I have conducted my first field trials. If there is anybody who has used this type of trap, I would be happy to hear about your experience.

As I have seen in a catalogue, the same trapping mechanism is used in the American VICTOR M313 'Mice' Trap. The company that sells this is the same that sells the Havaharts:

1e) Bulgarian wooden box traps
Date: Fri, 20 Mar 1998 00:54:06 +0200
From: lynx@bulnet.bg (Teodora Minkova)
In the Institute of Zoology in Sofia, Bulgaria, we have been working for many years with wooden-box traps. They are not quite sensitive to shrews but are very efficient for rodents. They are not produced by a company but by carpenters. I am not sure about the current price (last year one trap cost about 2.5$). If you are interested please contact me for more details.

1f) Havahart traps
Date: Thu, 26 Mar 1998 09:50:24 -0800
From: "Mary Smith" <v8350@bealenet.com>
From this page on their site: http://www.havahart.com/mice.htm
Model #1020 Dimensions: 10"x3"x3" This trap is recommended for Mice, Shrews and Voles. It has a gravity action door at both ends. This gives certain cautious species extra confidence to enter the trap because they can see through the end. Made with 14 gauge high tensile strength wire mesh and a galvanized steel frame.
2) Review of trapping methods

Dear shrewists,
I am looking for published reviews of trapping methods (live-traps) for small mammals (from a comparative point of view). Any references / leads will be appreciated. Any information you can supply would be of great value for field studies in the Crimean reserves.
Thank you in advance.

3) Baiting traps in the tropics
Date: Fri, 27 Mar 1998 11:29:08
From: Paul Meek <panres@ozemail.com.au>
Dear Colleagues
Does anyone have any tricks for shrew trapping (longworths) in the tropics?. We have immense problems keeping our bait of peanut butter, oats, honey and shrimp powder from growing with mould within a few days of placement. What are others doing to keep bait active and attractive ?.
Thanks in anticipation

4) Ether / Dye marking
Date: Thu, 16 Apr 1998 15:05:58 -0700
From: Stephen Petersen <ddansere@gpu.srv.ualberta.ca>
It was recently suggested to me that I might want to knock-out my shrews so I can handle them in the field better - I need to id them by dentition. He had used ether on woodrats. Has anyone used ether or anything else for this purpose? Any ideas? Also awhile back I asked for information on dyes I could use, one suggestion was Jamar and I was wondering where I could get product information on this dye.
Thanks Stephen

5) Dye marking
Date: Wed, 22 Apr 1998 11:43:24 -0400
From: Kara Vlasman <kvlasman@uoguelph.ca>
Subject: dye marking techniques for small mammals
I need a protocol for identifying individual small mammals such as deer mice and squirrels during observational studies. Due to their small sizes, I believe I need to resort to dye marking techniques. The study will last two summers however, I am hoping the dye markings will remain for at least one summer. Any suggestions on protocols that have worked well in the past and references that may be of use would be greatly appreciated.

6) Echolocation in Cryptotis parva
Date: Tue, 7 Apr 1998 06:07:19 EDT
I am currently working on my Masters in Biology and my research is on Echolocation in Cryptotis parva. While recording these animals we have noticed something rather particular. It seems as if they might be producing their ultrasonic sounds using their teeth. Before we begin to try and examine this possibility closely I wanted to know if anyone has noticed or even studied this behavior before. Might this be a reason for their red tipped teeth? I would greatly appreciate any input or suggestions anyone might have.

7) Reviving Blarina?
Date: Wed, 15 Apr 1998 11:54:08 -0400 (EDT)
From: Kathleen Logiudice <klogiu@eden.rutgers.edu>
I am a graduate student doing research on Peromyscus leucopus (the white-footed mouse) and I frequently capture Blarina brevicauda (short-tailed shrew) in my traps. Through the long, cold winter nights I checked the traps at midnight and again at dawn and never lost a mouse or shrew to hypothermia. Now that the nights are shorter and warmer, I am not checking the traps as frequently (I check once starting at 5:00 am) and I have had a couple of Blarina brevicauda mortalities. They were not dead when I got to the trap, but quite morbid and, although I tried to warm them up in my shirt, both died. I realize that they are probably starving as much as suffering from hypothermia and am wondering if I might be able to revive them with a glucose solution and a dropper bottle or some such easy-to-carry first aid. Do you think this would work or do you have any other suggestions? Any help you can give me would really be appreciated.
Thanks for your help. Sincerely, Kathleen LoGiudice

From: "jul pij" <juliettepijnakker@mailexcite.com>
I have a paper to do on "shrews on fields" for my horticulture school and i have to tell if the shrews we find in france make damages in the fields with their galeries and if they could eat sometimes some vegetables. i have to write if a shrew could eat slugs. (which species?) if i put it in my garden would the shrew be benefic or not? i know the shrew could eat the slugs but it would eat worms too. what do you think about it? and if i put a shrew in the greenhouse from my school, would it survive? (20°c and light) i would like to know too how i can keep shrews in captivity. how to feed it (babies and adults), what to do to for their comfort. i know that they are very active and they need a lot of space. if you have any information, articles about what i am searching for, please send them to me.
thanks. sincerely, juliette
