As the Shannon Dolphin and Wildlife Foundation (SDWF) reports, the dolphin known as 'No 1' was sighted in Brandon Bay on Saturday 25 May swimming in a group of three.
No 1 is happily a familiar sight in the region, having been recorded most years since the project began in 1993.
"It has long been known that Shannon dolphins regularly use Tralee and Brandon Bays but how important the area is in not clear," says the SDWF on its blog. "If we are to protect the Shannon dolphins we need to ensure we identify all their important habitats and extend protection to these areas if necessary."
Meanwhile, its been confirmed that the trio of bottlenose dolphins who took up residence near Bunratty Castle in the spring have been observed in the mainstream of the Shannon Estuary.
The three were spotted on the first monitoring trip of the summer from Kilrush last week by SDWF researchers of Moneypoint.
"This demonstrates again the value of long term monitoring and the power of a photo ID catalogue to monitor the Shannon dolphins," says the SDWF blog.
In other cetacean news, an in-depth discussion of the Shannon's dolphins and the Irish Whale and Dolphin Group's (IWDG) research of bottlenose dolphins around the Irish coastline was broadcast on Derek Mooney's afternoon show on RTÉ Radio 1 recently.
