Guarde los pelícanos

Okay, permite el cambio climático protesta o cualquier cosa que desee. Sin embargo, estamos preparados para ignorar la difícil situación de los pelícanos. No es el cambio climático, es simplemente el mayor desastre ecológico en Australia, todo por culpa de la mala gestión del agua. ¿Dónde están estos manifestantes en el momento. Tener un pensamiento café con leche que han tenido un gran día en la oficina todo porque se han lavado el cerebro en el tema. pelícanos y otras especies de peces se están muriendo y pronto podrían estar extintas. Bien hecho, Estoy orgulloso de mis colegas australianos.

pelícanos, ducks and other waterbirds in peril as drought’s grip tightens across outback

Pelicans and other waterbirds are dying in the outback and disappearing from waterways, as the effects of drought compound an already-concerning long-term decline in populations.

Puntos clave:

  • A dead pelican has been found a long way from water at an old railyard in South Australia’s mid-north
  • Pelicans can travel up to 3,500km in search of water, food and breeding grounds
  • Waterbird numbers at Lake Eyre have been surprisingly low after an influx of water earlier this year

Truck driver Lisa Lloyd said she was surprised to see a dead pelican in a railyard at Quorn, 40 kilometres north-east of Port Augusta in South Australia.

I was just wandering along on my horse and looked up and saw this great big black-and-white thing lying on the ground,” ella dijo.

It’s not something you see in Quorn.

The pelican had no visible injuries, Ms Lloyd said.

He didn’t look like he had been tortured, and the ground around him wasn’t upset in any way — he just looked like he stretched out and died.

Outback pelicans

Greg Johnston, an honorary research associate with the South Australian Museum, said the bird appeared to be an adult in good health but was not in breeding condition.

He suggested it might have been searching for water, adding that it was not unusual for pelicans to be spotted in the outback.

Probably with the drought happening, particularly in the eastern states, there’s not so much water around.

“Pelícanos se mueven distancias extraordinarias - se moverán hasta 3,500 kilómetros de una colonia de cría, para que pueda encontrar en cualquier lugar.”

Muerte, la sequía y el lago Eyre

Carta piloto Trevor Wright realiza vuelos diarios a lo largo de la cuenca Kati Thanda-Lago Eyre y dijo que no estaba sorprendido por el menor número de pelícanos y otras aves acuáticas.

“En comparación con años anteriores, definitivamente había una disminución en la población de pilotes en bandas,” él dijo.

“Había unos pocos bandadas de pelícanos en torno, pero creo que debido a la sequía las poblaciones de aves en general se han reducido.

The Australian continent definitely needs an increase in the amount of rainfall just to get the environment as a whole and the birdlife back to a sustainable level.

Hopefully we’ll get some drought-breaking rain over the summer period to bring the populations back.

Professor Johnston said pelicans often flew to Lake Eyre following an influx of water, but flooding that occurred earlier this year was not enough.

Usually there has to be water from flows down the rivers from the northern monsoons topped up by local rainfall, and we just haven’t had the rainfall to expect that kind of breeding event.

Possible extinctions

Professor Richard Kingsford, director of the Centre for Ecosystem Science at the University of NSW, conducts annual bird surveys across the Lake Eyre basin, the eastern seaboard and the Murray-Darling basin.

He said the Murray-Darling system drying up was another major reason why waterbird populations across the country were falling.

There’s been around about a 70 per cent decline [in waterbirds] over the past 30-odd years.

Those sorts of changes would obviously have big impacts given how important the Murray-Darling is both for the Lake Eyre basin and other places in Australia.

Professor Kingsford’s next survey of Lake Eyre is in October, but he is already receiving information from locals saying the number of waterbirds is surprisingly low.

In previous years we’ve seen an erratic number of waterbirds because they essentially arrive when the big floods come along, and then there’s hardly any when those systems dry out,” él dijo.

It’s a sort of silent wave of deaths that occurs during these very dry times.

Pelicans are not the only birds whose populations are suffering, Professor Johnston said.

Eastern Australian bird counts that are done by the NSW, SA, Victoria and Queensland governments every year, durante casi 40 años, que en realidad están mostrando una disminución muy constante en el número de patos, pelícanos, cormoranes y otras aves acuáticas,” él dijo.

“Nos están mostrando que nuestros humedales y nuestros sistemas fluviales están disminuyendo en calidad a largo plazo.

“Si el declive continúa, si no conseguimos nuestra gestión del agua en Australia resuelto, vamos a ver esos descensos continúan y el resultado final de que es la extinción de los animales.”
