However, based on the title alone, we can speculate on *possible* tones. The title suggests a somewhat alarmist or sensationalistic tone. The words "marauding" and "howl" evoke images of danger and chaos, while the phrase "just a howl from Madrid" implies a proximity of the threat to a major city, further heightening the sense of urgency or fear.
The actual tone could also be:
* Humorous/Satirical: The title might be used ironically to downplay a minor issue, making light of what might otherwise be considered a serious problem.
* Informative/Objective: The author might use the attention-grabbing title to draw readers in to a factual report on wolf population growth and its impact on nearby areas.
* Analytical/Concerned: The author could explore the issue of wolf populations and their interactions with human settlements in a balanced but serious manner.
To determine the true tone, you need to read the article itself.
