How to determine if a wild animal's behavior is "abnormal"?

Here is the translation of the provided answer content into English, maintaining the original Markdown formatting:

Hi, that's an excellent and vitally important question! Especially for those of us who enjoy outdoor activities or live in areas frequented by wildlife, learning to recognize normal behavior can not only help animals in need but also protect our own safety.

As someone who also frequently observes wildlife, I've summarized a few key points that are easy for the average person to identify. Remember one core principle: The greatest sign of "normal" behavior in wildlife is that they are afraid of people, avoid them, and remain constantly vigilant. Any behavior deviating significantly from this core principle warrants your increased caution.

Here are the points broken down clearly for you, using Markdown:

I. "Abnormal Friendliness/Approach" - This is the most dangerous sign!

This is the most crucial point to be wary of, especially as it is highly associated with rabies.

• Actively Approaches You: A healthy wild animal (such as a fox, raccoon, or weasel) seeing a person will have "run" or "hide and observe" as its first reaction. If it does the opposite—not running away but instead staggering towards you, or even appearing "friendly"—this is absolutely an extreme anomaly.
• Ignores Your Presence: You get quite close, yet it shows little to no reaction—neither fleeing nor attacking, as if it doesn't see you. This indicates potential issues with its perception or mental state.

Wildlife Tip: Consider any land-based wild mammal that actively approaches humans as potentially carrying the rabies virus or other diseases by default. Never touch it simply because "it looks cute"!

II. Disoriented or Bizarre Behavior

This is often a sign of neurological problems and is a classic symptom of rabies.

• Circling or Unstable Movement: The animal appears dazed, like it's drunk—staggering, unsteady on its feet, or constantly circling in one spot.
• Abnormal Aggression: Displays unprovoked, excessive aggression. For example, attacking its own body, trees, rocks, or any inanimate object frantically.
• "Staring Blankly" or Motionless: The animal may stand rigidly still, stare straight ahead vacantly, showing no response to its surroundings.
• Partial Paralysis: Hind limb weakness is common, sometimes dragging the back half when walking. You might also see a drooping jaw, unable to close its mouth, with excessive drooling (a classic rabies symptom).
• Making Strange Noises: Emitting vocalizations unusual for its species, or sounds that are hoarse or bizarre.

III. Presence at Unexpected Times or Places

Each species has its own behavioral patterns; breaking routine is a sign of abnormality.

• Nocturnal Animals Active During Daylight: For example, seeing a lethargic raccoon (common in North America) or weasel in broad daylight in an open area. While occasional exceptions exist (e.g., a mother foraging for young), it's highly concerning if accompanied by other abnormal behaviors listed above.
• Appears Where it Shouldn't Be: A deer in a downtown pedestrian zone, or a fox in a busy residential building hallway. This suggests it may be lost, disoriented, or so ill it has lost its sense of direction and danger assessment.

IV. Obvious Signs of Injury or Illness

These are visible health problems.

• Severe Hair Loss/Skin Disease: Patches of missing fur, with noticeable sores or lesions on the skin.
• Extreme Emaciation: Ribs and bone structure clearly visible, appearing listless and very weak.
• Discharge from Eyes or Nose: Crusty buildup around the eyes or mucus running from nostrils.
• Visible, Untreated Serious Wounds: Such as a broken limb or a large, infected, pus-filled wound on the body.

So, what should I do if I see an animal behaving suspiciously abnormally?

Remember these "Nevers" and this one "Always".

1. Keep Your Distance and Back Away Slowly! This is the primary rule. Don't succumb to curiosity and get closer to observe or take photos/videos. A safe distance is one from which you can disengage easily.
2. NEVER Feed It! Feeding alters natural behavior. For a sick animal, your proximity itself poses a major risk.
3. NEVER Attempt a "Rescue"! Unless you have specialized knowledge and equipment, do not try to capture or handle the animal yourself. You risk scratches, bites, disease transmission, or causing further harm to the animal.
4. [ALWAYS DO] Contact Professionals! This is the only correct action. You can:
   • Call your local Forestry Bureau, Wildlife Conservation Department, or Animal Rescue Center. In China, you can try calling 110 or the 12345 municipal hotline and ask to be connected to the relevant authorities.
   • Provide Clear Information: Tell them specifically when, where you saw it, what animal it was, and which specific abnormal behaviors it exhibited. If you can take photos or video from a safe distance (ensuring personal safety first), it can be very helpful.

Summing up the Core Principle:

What we should do with wildlife is "observe from a distance, never interfere." Their "normal" is maintaining distance from us. Any behavior that breaks this barrier of distance deserves our caution. Learning to recognize abnormal signs and promptly reporting them protects both ourselves and provides the most responsible assistance to these creatures.

Distance ensures both appreciation and safety. Hope this answer helps!
