Britain’s migratory birds ‘may stop flying south for winter’

Migratory birds including the willow warbler, the garden warbler and the nightingale may eventually stop flying south for the winter as they spend longer in their European breeding grounds.

Analysis of more than 50 years of bird records from the Gambia and Gibraltar has found that some migratory species that cross the Sahara are spending between 50 and 60 fewer days on average in Africa each winter.

The study, published in the journal Global Change Biology, examined changes in arrival and departure dates in the Gambia and Gibraltar alongside changes in climate and vegetation.

While it was previously thought that birds timed their seasonal migration based on daylight hours, the analysis suggests that birds are making more nuanced decisions based on available vegetation and climatic changes.

Records from 1964 to 2019 analysed by scientists at Durham University found that species were arriving at their winter destinations later in the autumn than in the past and also departing these locations earlier in the spring, reducing the amount of time spent in their winter homes.

Over a 27-year period, migratory birds including reed warblers, northern wheatears and common whitethroats were found to increase their time in Europe by 16 days on average.

Lead author Kieran Lawrence at Durham said: “If the trends we have seen in this study continue, we may see that, in time, some birds will spend no time at all in sub-Saharan Africa, and instead spend the full year within Europe.”

Many of these small migratory birds are suffering significant declines in their British populations, with nightingales in danger of extinction and England’s breeding willow warblers down by 45% in the past 24 years. But populations of chiffchaff, a short-distance migrant that mostly overwinters in Europe or north Africa, have increased by 114% over the same period.

While a reduction in migration could help some species survive, Lawrence said there were wider potential implications in both Europe and Africa. “In Europe, the longer presence of traditionally migratory birds could lead to increased competition for autumn/winter food and resources for resident bird species that do not migrate,” he said.

“Meanwhile, in the traditional migration destinations of sub-Saharan Africa, a reduction in the time migratory birds spend there could have implications for ecosystem services such as insect consumption, seed dispersal and pollination.”

Global heating has already changed some patterns of short-distant migration to Britain, with many more blackcaps now spending winter in the country rather than moving to continental Europe. In Europe, the white stork has reduced its migration to Africa, with many birds wintering on the Iberian peninsula rather than moving farther south.

Co-author Clive Barlow, a bird expert from the Gambia, said: “It is very satisfying to see the constructive way the Gambian migrant bird records, collected by dedicated ornithologists over many decades, are now being used to highlight the changing migratory patterns of these species. Until the current research, no one had realised the extent to which migrant birds are spending less of the year in sub-Saharan Africa.”

Alake Unveils Mining Marshals To Secure Mining Sites

In fulfilment of a major plank of his 7-point agenda to create a new security architecture to secure mining sites, the Minister of Solid Minerals Development, Dr. Dele Alake has unveiled a 2,200-strong Mines Marshal to smoke out illegal miners and all those who flout the nation’s mining laws.

Formally receiving the marshals drawn from the Nigeria Security and Civil Defence Corps (NSCDC) from the Commandant-General, Abubakar Audi, representing the Minister of Interior, Hon. Olubunmi Tunji-Ojo, Alake charged the new operatives to stem theft and all nefarious activities around the nation’s mineral resources so that the nation can reap maximum benefits from its God-given resources.

It will be recalled that as a result of the efforts of the presidential Inter-ministerial committee on securing natural resources chaired by Dr. Alake, the Minister of Interior, Hon. Olubunmi Ojo, a few weeks ago launched the NSCDC-led mines marshal, which represents the first layer of the new security architecture to secure the mining environment.

With a command structure spread across the 36 states and the FCT, the mines marshal will have their command and control domiciled in the Ministry of Solid Minerals Development(MSMD), with an initial 60 operatives deployed in each state and the FCT.

Highlighting the role played by his interior counterpart in the evolution of the new security outfit, Dr. Alake commended Hon. Olubunmi-Ojo for putting words to actions and working tirelessly with the solid minerals ministry to achieve the feat.

“Today’s event of unveiling and formally handing over the specially trained and selected civil defence structure to engage illegal miners and sanitise our mining environment was also part of what we conceived at the inter-ministerial committee chaired by me. I am very happy to let the public know that from the outset we said are going to tackle insecurity in the mining sector and the first batch of the security apparati is what we are launching today, the Minister added.

The mines marshal devised to be an inter-agency security outfit will incorporate special operatives from other security agencies like the Nigeria Police, army, amongst others. Its operations will largely be technologically driven.

In his remarks, NSCDC Commandant-General, Abubakar Audi stated that the new mines marshal will give verve to the corps’ mandate of protecting national assets and infrastructure in which solid minerals is a major component.

Audi revealed that the marshals will liaise with mine inspectorate in states to garner intelligence and take directives from the ministry for effective execution of its mandate.

“We have a list of illegal miners across the nation, and we will go after them. Their days are now numbered, “Audi declared.

The Chairman, House Committee on Solid Minerals, Hon. Jonathan Gbefwi, who graced the occasion, expressed satisfaction with the new security outfit, noting that with improved security around mining areas, Nigeria’s economic fortunes is bound for a forward leap.

” When the Minister reeled out his 7-point agenda during his inaugural address, which included the Mines Police, not a few people were sceptical about it. But today, he has matched words with action. On behalf of the people of the Federal Republic of Nigeria, I doff my hat for him and say, “Well done.” You can be rest assured of the continued support and cooperation of the House of Reps and, by extension, the National Assembly, Hon. Gbefwi said.

The new Mines Marshal is led by a Commander, Chief Superintendent of Corps, CSC Attah John Onoja.
