    Hi Betty

    Yes, the behavior you are describing is normal swan behavior in cygnets that are now ready to mate and have no idea how to deal with the increase in sex hormones. We have seen mating behavior in cygnets as early as 1-2 years of age. Are all of of your swans clipped? Are there any predators in your lakes that a clipped swan cannot escape? If the answer is yes to question number one, then you might consider clipping and relocation to another area pond. However, if the answer to predators is yes and no escape, you need to consider which lake you can safely relocate because relocation can result in serious injury or death to the cygnets if they cannot fly and escape predators. Sex hormone levels should return to normal levels in a few weeks and the cygnets’ behavior will settle. The Regal Swan

    Hi Marco

    We apologize for the delayed response, but we have been updating the website. There are several possibilities for the ring-like appearance around the neck. One reason could be that the swans are coming into contact with something under the water and are rubbing against the object causing an abrasion. The second possible cause is a parasite, protozoa or fungus in the water that is infecting the swans. The swans would need to be captured and examined by a licensed veterinarian to determine if an infectious agent is the cause.

    However, more than likely, the cause of the lost plumage in this area is from swans pecking at each other during fights for mates and territories as springtime brings out defensive behavior. As long as there is no infection, the plumage should return very soon. Again, if this is an infection, a veterinarian should be consulted. The Regal Swan
