Post-capture evaluations are rarely practiced by wildlife professionals, yet they provide enough benefits for animals and field biologists to justify becoming a part of any wildlife capture program. During our wildlife captures in collaboration with the Red Wolf Recovery Program, scrutiny from the public, executive staff and policy makers was intense and it required me to develop a practical approach for self-evaluations and official documentation. This practice became so valuable for each biologist on the project that I now integrate it into all of my animal handling programs.


Here is how our project team evaluated our own field captures…. While trapping for large sympatric canids, the need to document our capturing techniques and processes for each capture arose from both the socio-political sensitivity of the work and the broader background issues surrounding red wolves, coyotes, and their hybrids. Our trapping took place during a time when support for North Carolina Wildlife Resources Commission’s involvement with large sympatric canid work in this area was not universal. I was receiving many questions about how and why I was doing what I was doing, despite having a fully developed project plan. I found my own memory to be shaky and often unreliable. It can be difficult to recall minute details while in the midst of a busy trapping season. The time needed to locate information in my files was often consumptive when other’s expectations for receiving answers were of a more urgent nature. This led me down the road to developing and incorporating the practice of creating post-capture reports into my trapping work.


A Game Changer


Spending the time to develop and incorporate this practice was a game changer for my work. It provided our team with several valuable benefits:

  1. We now had a complete, detailed record of our actions and justifications that were easily referenced.
  2. It gave my staff and me the opportunity to reflect on the actions taken, what went well and what could be improved, and what actions in the future could be done differently.
  3. It gave me the opportunity to discuss our field captures with collaborators, managers, and other high level leadership to receive their input.
  4. It gave us a broader understanding of what we were learning as we went through each capture experience. It’s become a strong positive feedback cycle in our work.

Post-capture evaluations strengthen our ability to learn from every animal and every field operation.


Creating a Post-Capture Report

While it would be easier to simply have a written description of what occurred, creating a package of proof is more powerful when answering hard questions. In the case of my canid research, we needed to document data, photos, and videos when possible. In your reports, I recommend including:

  1. A written, detailed description of what occurred in the field,
  2. A scan of your capture data sheet, including TPRs(temperature, pulse and respiration),
  3. Maps of your capture and release sites
  4. A map of initial GPS collar data (if using GPS collars) or initial telemetry triangulation data
  5. Photos of the release

Remember that animal care and ethics are the basis for this post-capture evaluation. It is not sufficient today to simply cite IACUC recommendations in project plans (something I see frequently when reviewing Scientific Collection Permits). Creating a foundation of animal care and ethics relies on documenting a project ethos, detailed impact and risk assessments, and mitigation and contingency plans, before ever stepping into the field. The post-capture practice will only be as good as the foundation it is built upon. Remember that post-evaluations for your own self-assessments are justification enough. They can be shared with your colleagues to get other professional opinions on how to improve. I strongly recommend that you take the time to evaluate each capture. The extra time to assemble a self-evaluation, followed by a series of discussions is time and effort well spent at both the front and back ends of a project. Doing so garnered our team trust, confidence, strengthened our field procedures, and minimized perceived controversy among those receiving our reports.

"Dear Colleagues, I'm proud to announce that my wife, Elizabeth, has published her first book! In this blog article, Elizabeth describes how the five Chinese elements can help us "know our dog's true nature". This is a fun way to better understand your dog and better know yourself and your colleagues! Both Elizabeth and I, with domestic animals and wildlife, teach others how to better understand the animals, how to better care for them, and what the animals can teach us. Have fun with this!"

Here is a great question sent to me from a wildlife biologist taking my online course, “The Foundations of Wildlife Chemical Capture”. Dr. Mark Colleen asks: Dr. Mark, I just finished Chapter 2 where you discussed the importance of accurate weight estimates to determine safe and effective immobilizing drug doses. I see you mentioned observing the ear size in relation to the body, but what are your other go-to observations for estimating body weight for bears? Dr. Mark’s reply: Great question. I have three predominant aspects that I consider when estimating body weight for bears: Ears give me a sense of how old the bear is. As bears grow, their head grows but their ears do not. So a big-eared bear is a small younger bear. A bear with little ears (relative to head size) is an older larger bear. We’re often estimating bear weights when they are in a culvert trap so I first notice if it is a large or small culvert trap because traps vary in size. A small culvert trap will make me think it is a larger bear and can skew my estimate. A larger trap will make a bear look smaller. My strongest reference is writing down my weight estimates on the drugging field form every time we do a capture. We also document actual weight as well. That way we are learning from every animal. When I have a partner at the capture, I ask them to also write down their weight estimate. After we weigh the bear, we know that whoever is least accurate buys the next coffee. It is interesting to note that we have always strived for being accurate with animal weight estimates within 10%. That is the professional standard. I realized that we strive to be accurate within 10% because when we work with ketamine/xylazine and Telazol combinations (which I have done for decades), small variations in dose really makes a difference in the downtime and depth of immobilization. Many biologists are now immobilizing bears with BAM and BAM is more forgiving. We can be 25% off in our weight estimates and not notice a difference in the immobilization. One major reason for this with BAM is that we have reversals to wake up an animal when we’re done. With ketamine/xylazine and Telazol combinations the anesthetics are not reversible. With Telazol, we have to wait for them to wake up and we must wait for ketamine to wear off before we administer the reversal for xylazine. So we don’t want to give them any more than we need to, but we want to be confident that we gave enough! In all cases, we still strive to be accurate within 10% for safe and successful wildlife immobilizations. To recap: Look at the ears Look at the culvert size Write down both estimated weight and actual weight on the field form so we learn from each animal. Care to learn more?
