I see where the Sequoyah National Wildlife Refuge is now using Propane Cannons in the open fields. I was told that they are trying to keep the wild Hogs out of the fields so that the crops can get established.

This past weekend I was at the Refuge and I heard a cannon going off. I had a feeling that this was going to have an effect on all the wildlife, and I was correct. I didn’t photograph anything but birds. I did see deer and one Coyote, but they were nervous, and I was unable to get a good photo.

I look forward to coming to this Refuge during the Spring because this has been my most productive time to see and photograph wildlife.

I understand that the hogs need dealt with and I have seen first hand the damage that they do. I will continue to go to this Refuge but not as often as I like.

Update from the refuge:

“ We have been trying to shut the cannons off during the day. But this past weekend I had no one available to shut them off. We killed 315 hogs on the helicopter shoot and over 900 in the last 12 months.”


How I Got The Shot

I was using a Fujifilm X-T3 camera with a Canon EF 100-400 mm f/4.5-5.6L IS II lens attached with a Fringer EF-FX Pro. I was shooting in aperture priority mode (AV) with a shutter speed of 1/550 of a second at f8 and the ISO at 160. White Balance was set on auto. I was using zone AF and the 3×3 box, continuous auto focus with multi metering.
