The El Acebuche Iberian Lynx Breeding Center, in the Doñana National Park has registered four litters with 11 cubs born this 2021 breeding season which has now finished. This is double compared to last year even though of the 7 pairs at the centre only 4 females gave birth. The eleven cubs are in perfect health though there is one that is being hand reared as the mother showed no interest in caring for it.
Last years 2020 breeding season for the Iberian Imperial eagle (Aquila adalberti) has seen some excellent results with. There are new nesting pairs of Spanish Imperial Eagle in Andalusia and 138 hatchings were recorded in Andalusia with 122 leaving the nest successfully and only 13 cases of mortality. Most of the breeding pairs of the Iberian imperial eagle in Andalusia are located in the province of Jaén, where there are 50, while the province of Cordoba is in second place, with 32 pairs, and then Seville, with 27. The rest It is distributed between those of Huelva (6), Cádiz (5) and Granada (3).
This increase in new distribution areas in the provinces of Granada, Cádiz and in the Sierras Béticas of Jaén consolidates the viability of the Andalusian population, while the number of couples in Sierra Morena has grown, which has made it possible to unite the eastern and western sub-nuclei, increasing the population of the province of Seville by five pairs, where a population decline had been detected in recent years.
The breeding success of 2020 was certainly helped by the confinement due to the Covid-19 health crisis and the closure of sites where nesting took place which has reduced human disturbance to the reproductive pairs. Nesting habitat is usually dry, mature woodlands, which they utilize for nesting and seclusion, but nests are most often fairly close to shrubby openings and wetland areas where prey is more likely to be concentrated. A shy species, they normally nest only where human disturbance is quite low.
A recent survey studying the impact of Iberian wild boar in the Tablas de Daimiel National Park has come to the conclusion that the population causes a serious threat to the ecosystem and threatens the reproductive success of aquatic birdlife in the area.
The Complutense University of Madrid and scientists from the Research Institute of Hunting Resources (IREC) has published the study in the journal Ecological Indicators, points out that the increase in wild boar that is taking place in almost 80% of the wetlands in Castilla la Manchaalso affects adversely the population of the wild rabbit, which is a key prey food species for many threatened top level predators
The research has shown that the wild boar, thanks to its characteristics as an omnivorous, prolific and highly adaptable mammal, is expanding in the twenty-six wetlands analyzed, especially in the Tablas de Daimiel National Park, where its impact is reaching “ unsustainable levels”, warn the authors adding “The protection of certain environments and especially the absence of hunting favor the proliferation of wild boar, which has a cascading effect on the entire ecosystem.
Well, the Iberia Nature Forum continues to (re) grow and it’s great to see a few people taking some time away from the major social networks to add their input to a fully searchable forum (Where your posts don’t get lost) about the wildlife and natural history of Spain.
The photo above is of a black vulture with news appearing on various channels today of this species nesting in Aragón for the first time in 100 years….. 🙂
Such a shame to see that the diclofenac topic rears its ugly head again with the news that vultures are dying in Spain due to diclofenac poisoining. (Diclofenac was approved in Spain and other European nations in recent years because farmers, drug companies and regulators argued that cattle carcasses were disposed of differently in Europe than in India. This meant vultures would not be able to eat meat tainted with diclofenac.)…. https://iberianatureforum.com/forums/topic/diclofenacnsaids-and-the-threat-to-iberian-vultures/
Such a shame that we still have this issue after decades. Diclofenac seems to have killed the first vultures in Spain many years after the Asian populations were virtually wiped out by this drug used by vets.

Fantastic footage observing fin whales using drones off the Catalan coast. These researchers are using drones to film and record behaviour that can’t be observed from the deck of a boat.
The fin whale (Balaenoptera physalus), also known as finback whale or common rorqual and formerly known as herring whale or razorback whale, is a cetacean belonging to the parvorder of baleen whales. It is the second-largest species on Earth after the blue whale.
