The Southern resident killer whale population is on the brink of extinction, but it seems, not for the reason that people thought.
Found along the coast of Washington, Oregon, California, and British Columbia, this population is thought to number just 75, but births are rare, and often end in sadness. 2 calves have been born in the last 2 years, but both have died young. This year, the mother was seen carrying her dead infant for some time (draped across her snout).
It is thought that this population is in danger as a result of a collapse in the Chinook salmon which is an essential part of their diet. However, this theory is defeated, when we look at the Northern resident killer whale population, and notice that they appear to have less access to the salmon. There is lots of shipping noise in their home, which may mean that they are incapable of communicating, which would impact their ability to hunt,
It is true that the origins of their decline lie around 120 years ago, when blackfish (orca as they were then called) were both slaughtered and captured for marine parks. The population on stopped falling fast when Canada banned capture. So is this just the straw that broke the camels back?
Why do captive orca have drooping fins?
Drooping dorsal fins are occasionally seen in the wild, so the split is not totally solid, but it is true, that while most captive orca eventually have a drooping dorsal fin, this is a far rarer site in the wild (while not being unheard of).
The fin is supported by a tough protein called callagen, and it has been suggested that with captive orca spending more time at the surface, the higher temperature from the sun may degrade the protein.
Tahlequah has given birth again (famous for carrying her first calf after it died)
Tahlequah carried a former calf for 17 days after it died, and for more than 1000 miles. This means it is rather lovely to see that she has had another calf. However, the calf has already been observed being pushed by the mother and does not look healthy. The mother is very experienced, so it is hoped that she can succeed, but time will tell. This mother is part of the Southern resident population which i mentioned above, which is small and with few births in recent years. It is therefore very concerning to find that 2 related calves died so close together.
A new video shows a mother orca teaching her calves how to hunt
I should say, that the article I read suggested this was the first time that it had been seen, but the below clip is from several years ago. Even so, it is fascinating to see a mother actively teaching her offspring how to hunt/
Orca have been seen, for the first time off Chile, hunting dolphins
As can be seen from the video above, orca are known to hunt and eat dolphins in various places around the world. However, this behaviour has never been seen in this population, so they had to work out how to do it for themselves. While in the past they have been filmed eating sea lions (and using local boats to hide their approach), they have now been filmed hunting dusky dolphins.
The study was looking at the eating habits of orcas in the southern hemisphere, so as to be able to conserve them more effectively. It suggests that Chile Orca are turning to these food-sources. While Orca have been filmed harrasing or even killing porpoises and dolphins, this is the first time that they have been filmed eating them.
Orca facing uncertain future as the marine zoo shuts
Marineland Antibese near Cannes France, is shutting, after the French government brought in more strict rules of their care. The law was passed in 2021, but comes into force in 2026. It is thought that 90% of the visitors come to see the killer whales and other dolphins, so without them they are not viable.
It is unclear as to what will happen with the Orca. They are from Icelandic waters, but having spent so much time in captivity, would not be able to look after themselves in the wild. A deal had been made to send them to a Japanese park, but there was outcry as their treatment would be worse, so the French government blocked it. There is another zoo in the Canary islands. A facility in Eastern Canada has suggested netting off around 40 hectares of a sea bay for them, where they could live out their lives, in relative comfort, and yet still be looked after by a team of vets and other carers.
Something similar has happened before. Keiko was the orca from the film Free Willy, and was rescued from captivity in 1996 and released into a similar bay in Iceland in 1998. Having spent more time in the wild, though he was able to relearn some skills and in 2002 he left with some wild orca. He swam to Norway, but unfortunately died from an infection in 2003.












many as 70 subspecies, local variants and similar have been suggested, however there is only one currently recognized species.
















The red-fronted Gazelle is found in a wide but uneven band across the middle of Africa from Senegal to north-eastern Ethiopia. It mainly lives in the Sahel zone, a narrow cross-Africa band south of the Sahara, where it prefers arid grasslands, wooded savannas and shrubby steppes. There are some people who consider the more famous Thompson gazelle of east Africa a subspecies of the red-fronted Gazelle.
Also known as the Rhim gazelle, African sand gazelle or Loder’s gazelle while its name in Tunisia and Egypt means white gazelle, it is pale and well suited to the desert, however there are only 2500 of them left in the wild. Widely found, they have populations across They are found in Algeria, Egypt, Tunisia and Libya, and possibly Chad, Mali, Niger, and Sudan (this can be seen on the map opposite).

The Speke’s gazelle is the smallest gazelle and is found in the horn of Africa (Somalia and Ethiopia – though hunted to extinction in Ethiopia). They number roughly in the low 10,000s. Unfortunately having been hunted to extinction in Ethiopia, its one remaining home is a war zone, which does not give us reassurance that it will survive into the future. While the population has increased in recent times, the animal has recently been upgraded from vulnerable to endangered. It takes its name from John Hanning Speke, who was an English explorer in central Africa. It is similar to the Dorcas gazelle, and it has been considered a subspecies at times.



Also known as the Clarkes gazelle, it is another species restricted to Ethiopia and Somalia. It is not a true gazelle, though it does still have markings on its legs similar to the gazelles. They are classed as vulnerable, with their biggest threat being poaching.








A small antelope, though found across a wide range of habitats. They are secretive, and as such are generally seen far less often than their population would suggest. They are rarely seen in the Kruger, but overall are not doing badly.



The Sharpe’s Grysbok, is another small antelope that is found in the east of southern Africa (its most southerly point is the northern Kruger. As a small species, however, it is another antelope that can regularly pass without notice.



















The Arabian Tahr is a species of Tahr found in eastern Arabia. They were recently moved to their own genus Arabitragus. It is the smallest Tahr species, and both genders have rear facing small horns. They have longish fur of redish brown fur, with a black stripe running down its back. They live in the Hajar Mountains in Oman and the United Arab Emirates, at evelation of up to 1800m.




Thy Himalayan Tahr is another species of Tahr found in the Himalayas in southern Tibet, northern India, western Bhutan and Nepal. It is listed as Near Threatened on the IUCN Red List, as the population is declining due to both hunting and habitat loss – with the population in its native range thought to be around 2200.






The Nubian Ibex has a relatively restricted range (as can be seen from the map to the left). The population across this area is under 5000, with the largest population in Israel (1200-1400). It is considered vulnerable. Their population has remained surprisingly stable over the last 10,000 years as the advent of domestic animals came in. Nubian Ibex, like other Ibex species take refuge on impossibly steep cliffs, and are more and more viligant the farther they are from these safe zones. This nimbleness also allows them to climb trees.

The west Asian Ibex (often referred to as wild goat) has the range shown on the left. It inhabits forests, shrubland and rocky areas across this range. It is classed as near threatened, largely as a result of degradation and destruction of their habitat. It is thought to be the ancestor of the domestic goat.










Also known as a Thar, It is the official state animal of the Indian state of Mizoram. It has at various times been considered a separate species in its own right. At the moment, it is thought to be a subspecies of the mainland Serow, however it has moved back and forwards in recent years, so we will list them all.



This map shows the range of all serow species (or subspecies) the Southern Serow, inhabits the grey range that is lowest on the map. They are classed as vulnerable to extinction. There is no estimate for them across their whole range, but the population of Malaysia is thought to be between 500-750.

The Taiwanese Serow (also known as the Formosan Serow) lives on the island of Taiwan. It is classed as least concern, but there is no concrete estimate on its wild numbers. Generally browsers, they are very shy, and are usually not seen, merely known of there prescense from their droppings.




The aardwolf is the smallest member of the Hyaenidae family, as you can see from the map, it is a species with two separated populations, one in East Africa and one in Southern Africa. It is insectivorous, and exclusively nocturnal, and is generally thought of as one of the harder animals to see in the wild. If incredibly lucky, you can see them feeding alongside Aardvarks, and even Pangolins, but this is rare. They favour open dry plains and savannahs.
