This rambling is leading up, albeit very slowly, to the subject of today’s blog which is actually about the Big Blue Heron that over the years has, at times, helped himself to a free meal at my fish’s expense. We have constantly had run ins with my goal to keep the bird away or at the very least make it difficult to get close to the ponds and it has become a real battle of wits. Whether it is the same bird or a constant stream of them, I am not to know. Wonder what the average life of a heron is?
Years ago when I first started having the Heron problem, I tried all kinds of things to make it difficult for the Heron to fish. I always understood that the birds would walk up to the water and then step in to do their fishing. Some people install trip wires located a few inches off the ground. I don’t know if they work as I have never tried them. Instead, I put 4 ft high wire fences around all of the ponds and then electrified them with a doggy shocker that would make the heron wary and hopefully deter it. This worked for a while until the heron figured that it could fly over the fence and land directly in the shallow water, totally contrary to my earlier beliefs. Of course, it couldn’t do that to the deeper ponds and I do have a video of a heron, who must have visited the Round Pond the year before when it was shallow. Now, a year later, not realizing that it is almost 4 feet deep after I had rebuilt it, struggled mightily to get up and out of the water. He still had enough wits to grab a fish as he flew up
Finally, I added water powered Scarecrows that are activated by motion detectors and placed one on the Round Pond and the other on the Small Pond. These things work very well and are noisy besides sending out a strong jet of water, enough to frighten the bird. The downside to them is that they go off at the slightest movement, whether it be the wind blowing the vegetation or me or the dogs passing in front of them. Consequently, my water bill goes up to $40.00 a month or more from the usual $17.00 when I have them activated. So, I only use the scarecrows when I know that there is a Heron Alert in our neighborhood. I have friends who very kindly alert me when the heron is around.
Based on my previous experience, the Heron usually is the most active in February and March probably because it has a nest with young that need feeding. This year, with so many of the ponds in the area dried up from the lack of rain, I was constantly on the lookout just in case. My neighbors from around me in the area usually text each other when they spot the big bird which was exactly the case this time around. My immediate next door neighbor did just that but the problem was that I was driving and was 20 miles from home and didn’t read the text until I arrived back. By then, the heron had come and gone. I forgot to mention that I have video cameras up in the trees focused on each of the ponds and the heron activated them. Well, the truth is that everything activates them including the wind making the vegetation sway, rippling water, birds and even the fish as they swim around and not forgetting myself and the dogs as we get wet as they go off. This means that I have to scroll through a lot of these two minute downloads on the disk in order to locate any big bird activity. One reason that I knew the Heron had visited was the fact that the goldfish in the Round Pond were not visible and would not come up to feed. They usually only go down and stay down when something spooks them.
Sure enough, when I went back indoors and started reviewing the memory card from the camera system, up popped my friendly Heron in all of his glory busy with a smorgasbord of Goldfish and Koi. He first tried to catch a goldfish by leaning over the Round Pond wall but it gets away. His next move is to hop up onto the wall of the Round Pond trying to catch a fish before eventually walking around the pond and then hopping down into the shallow water of the Small Pond where he managed to catch at least two fish. The last one being one of the bigger ones in that pond of at least 12 inches in length. He really struggled to turn and swallow that fish as the video shows close up and you can see the bulge in his neck where it has lodged. Whether that is its way of carrying the fish back to the nest to regurgitate or is the natural way for its own consumption, I wouldn’t know. Bottom line was that big fish was enough for the bird to complete its meal as it took off almost directly after swallowing its prize.
Needless to say, I have now activated the Scarecrows in the hope of deterring the Heron from making future visits. I plan on closing down the shallow pond and putting it out of commission, filling it in and turning it into a lawn. I will keep just the waterfall activated as a pretty water feature. In the meantime, I will catch the Koi and Goldfish and distribute them between the other 3 ponds so at least hopefully, no more of them will be Heron food in the future.
The Heron really is a beautiful bird and is very impressive with its almost 5 feet wingspan. Kinda reminds me of a Pterodactyl of yesteryear and from the fish perspective, just as dangerous. By the way, there is a Heron statue on the Round Pond so don’t confuse that with the real bird.
