Rare cannons from Spanish Armada discovered in seabed after wreckage from ship washed ashore by storms

Relics from Spanish Armada discovered in Sligo

Artefacts more than 425 years old from merchant vessel found off Streedagh

Severe winter storms over the last two years are believed to have led to the recent discovery of relics from the Spanish Armada off the Irish coast.

A number of cannons from the merchant vessel La Juliana have been found in sands off Streedagh in Co Sligo since timbers from the exposed wreck began washing ashore in April.

The guns date back to 1588 but are said to be in excellent condition.

Two have been taken off the seabed with archaeologists discovering that one bears a dedication to and depiction of St Matrona, a saint particularly venerated by the people of Catalonia.

It is also dated 1570, the year La Juliana was built, putting the identity of the ship beyond doubt, the Government said.

Heather Humphreys, Minister for Arts, Heritage and the Gaeltacht, visited the wreck site and saw the archaeological work first hand.

“We have uncovered a wealth of fascinating and highly significant material, which is more than 425 years old,” she said.

“This material is obviously very historically and archaeologically significant.”

Two other vessels from the Armada sank in violent storms in the area in September 1588, La Lavia and Santa Maria de Vision, with more than 1,000 soldiers and mariners drowning when they went down.

They are believed to remain concealed and protected by layers of sand which did not shift in storms over the last two years.

La Juliana traded between Spain and Italy until King Philip II commandeered it for the Armada fleet of 130 ships to invade England and take Queen Elizabeth I’s throne.

The vessel was large, weighed 860 tonnes, carried 32 guns, 325 soldiers and had a crew of 70.

Recovery of the rest of the guns, relics and materials from the sandy seabed off Sligo is expected to last a number of weeks.

Ducks wintering in Spain, from where?

Geographical origin of dabbling ducks wintering in Iberia: sex differences and implications for pair formation

Natural and anthropogenic Iberian wetlands in southern Europe are well known for supporting large numbers of migratory Palaearctic waterbirds each winter. However, information on the geographical origin of dabbling ducks overwintering in these wetlands is scarce and mostly limited to data from ringing recoveries.

Here, we used intrinsic isotopic markers to determine the geographical origin of male and female Northern Pintails Anas acuta and Eurasian Teal Anas crecca in Extremadura, inland Iberia, a key site for overwintering dabbling ducks. Additionally, we fitted six Northern Pintails with GPS-GSM tags to complement the data derived from stable isotope analysis.

Most (> 70%) first calendar-year Northern Pintails were assigned to regions above 55°N, flying 2600–5600 km from their main natal regions to Extremadura. Mean values of δ2Hf varied significantly between male and female Northern Pintails, suggesting that the sexes had different geographical origins. Data from tagged adult Northern Pintails supported the isotopic data, one male flying more than 5000 km to the coast of the Pechora Sea (Russia). Most (> 70%) first calendar-year Eurasian Teal were assigned to the region between 48° and 60°N, travelling 1500–4500 km to arrive in Extremadura.

Male and female Eurasian Teal showed marginal differences in mean values of δ2Hf. In migratory dabbling ducks, pairing typically occurs on the wintering grounds, and ducks in their first winter can breed the following spring. For Northern Pintails, pair formation in Extremadura could occur between individuals with different geographical origins, which could contribute to the genetic variability of their offspring.

Abstract:

Rallids are good biological models to monitor anthropogenic changes to wetlands. The distribution of the Rallidae was mapped up during a survey of all major wetlands across Algeria and nest site selection, phenology, and breeding parameters of the Purple Swamp-Hen Porphyrio porphyrio were monitored at two distinct sites under contrasting conditions. Data were collected at Boussedra, an unprotected freshwater marsh during the years 2005 and 2008, and at Lake Tonga, a protected freshwater marsh during 2009. The onset of egg-laying was found to occur earlier (mid-February) than was recorded previously (end-March). There was much variation in the egg laying patterns and in the clutch sizes which dropped significantly…
