Summary:
1. The North Atlantic right whale calving season ended with only 11 mother-calf pairs, a cause for concern.
2. The population of North Atlantic right whales is critically endangered, and the number of calves born each year is declining.
3. Scientists have documented a significant decrease in the number of right whale calves in the last decade compared to the previous one.
4. To sustain the species, an average of 22 right whales must be born each year, which is a challenging target.
5. Visit our blog to learn more about the 11 mother-calf pairs documented this season and the efforts to protect the North Atlantic right whale.
Last month, the North Atlantic right whale calving season ended, leaving conservationists and scientists concerned about the future of this magnificent and critically endangered species. With a total of only 11 mother-calf pairs documented, it is evident that the population of North Atlantic right whales is rapidly declining. This news is a stark reminder of the challenges these magnificent creatures face in their struggle for survival.
For the past decade, scientists have been monitoring the birth rate of North Atlantic right whales, and the results have been alarming. In the last 10 years, only 108 calves were born, while the previous decade saw 216 newborns. This significant decline in calves poses a serious threat to the long-term survival of these gentle giants.
According to our right whale scientists, an average of 22 right whales must be born each year to reach the numbers of the previous decade. Achieving this target seems increasingly challenging, considering the steady decline in calf births. The critical issue is the need for conservation efforts to restore the population and ensure the species’ survival.
The circumstances surrounding the low birth rate of North Atlantic right whales are multi-faceted. The main threat to their survival is human activity, particularly collisions with ships and entanglement in fishing gear. These factors, habitat degradation and noise pollution, have created a hostile environment for these magnificent creatures.
The impact of ship strikes on right whales cannot be underestimated. The sheer size of these animals and their slow movement make them particularly vulnerable to vessel collisions. To combat this problem, efforts are underway to enforce speed restrictions for ships in areas where right whales are known to migrate and calve. This is crucial in minimizing the risk of accidental collisions and preserving these gentle giants.
Another significant problem facing North Atlantic right whales is entanglement in fishing gear. The ropes and nets fishermen use can tangle around a whale’s body, leading to life-threatening injuries or painful deaths. To address this issue, collaboration between scientists, fishermen, and policymakers is essential to develop fishing practices that minimize the risk of entanglement while ensuring a sustainable livelihood for fishermen.
Beyond human-induced threats, the health of right whales is also influenced by the availability of their primary food source – plankton. Changes in ocean temperatures and climate change can significantly impact plankton distribution and abundance, thereby affecting these whales’ nutritional well-being. By understanding and mitigating the effects of climate change, we can strive to create a more favorable environment for the survival and reproduction of North Atlantic right whales.
Amidst these challenges, there is hope. Scientists, conservation organizations, and policymakers are working tirelessly to protect and restore the population of North Atlantic right whales. Efforts include using aerial surveys to monitor whale populations, implementing regulations to reduce the risk of ship strikes and gear entanglement, and advocating for protected areas where whales can thrive undisturbed.
The 11 mother-calf pairs documented in this season are a testament to the resilience and power of these creatures. Each new calf represents a glimmer of hope for the future of the North Atlantic right whale population. By learning more about the stories behind these 11 pairs and the efforts to protect them, we can all contribute to the conservation of this remarkable species.

Source Description
Last month, we ended the North Atlantic right whale calving season with 11 mother-calf pairs.
Although our scientists are celebrating these new calves, the number of mother-calf pairs documented is far below what is needed to sustain this critically endangered species. In the last 10 years, scientists have documented 108 calves born, while the previous 10 years produced 216 calves. According to our right whale scientists, we would need an average of 22 right whales born each year to reach the previous decade’s numbers.
