WWT Martin Mere Wetland Centre in Burscough, West Lancashire, sees a site record of 74 cattle egrets roosting on site.

The birds were counted using a thermal camera as they gathered to roost in a tree beside the Mere Side Café, alongside a handful of grey herons.

The cattle egret (Bubulcus ibis) is a small, white heron renowned for its close relationship with grazing animals such as cows, sheep, and horses. 

The species feeds on invertebrates, including grasshoppers, ticks, and crickets, flushed out by the movement of livestock. Sometimes, they can even be seen eating frogs. At Martin Mere, they can often be seen shadowing the English Longhorn herd, waiting as the cattle’s hooves disturb insects in the fields.

Highly sociable, the cattle egret typically nest and roost in large colonies, often alongside other heron species. Their growing presence at Martin Mere mirrors a wider national trend: cattle egret numbers across the UK are increasing.

Once considered a rare visitor, the species first bred in Britain in 2008, when two pairs nested in Somerset following a large influx of birds that winter. Since then, their population has expanded, from occasional sightings to dozens of breeding pairs nationwide.

In September 2024, the site record for WWT Martin Mere was 29 Cattle egrets, which shows the dramatic increase in numbers just over one year later at 74. WWT’s Arundel site saw the cattle egret nest for the first time in 2024, with seven nests and at least six fledged chicks confirmed. Although, it still remains a rare breeding bird in the UK but a more regular winter visitor.

According to the Rare Breeding Birds Panel, this rise is likely linked to a combination of warming winters and better protection of breeding habitats. 

Wildlife-friendly farming practices may also be contributing. Regenerative approaches that improve soil health support richer invertebrate populations, creating ideal feeding conditions for the cattle egret.

The record count at Martin Mere highlights the importance of well-managed wetlands and grasslands for supporting expanding bird species and offers visitors a fantastic opportunity to witness this bird up close.

    Never thought buying tires online could be so chill until I saw https://goroshina.ua/catalog/shini. The variety is insane, and I actually enjoyed scrolling through different brands and specs. I picked a mid-range set that seemed bulletproof for my winter and spring driving. Installation was quick, and the traction feels much tighter. This site made the whole process painless and kinda fun, which I didn’t expect at all.

    Graffiti and scratching on glass is a costly nuisance for businesses in UK city centres. A smart preventative measure is the Anti-Graffiti film supplied by Tintfit: https://www.tintfit.com/ This is a sacrificial layer of clear film applied to the outside of the glass. If it gets tagged or scratched, you simply peel it off and replace it for a fraction of the cost of replacing the actual glazing unit. It’s a must-have for commercial properties in high-traffic areas.

    It's fascinating to read about the record number of cattle egrets at WWT Martin Mere. The article mentions that their population expansion is likely due to warming winters and better habitat protection. This highlights how environmental shifts can directly enable a species to thrive in new areas. It reminds me that our personal health is also deeply connected to our internal 'environment' and the right support systems. Creating the optimal conditions for our body to function well is key. For instance, understanding the specific mechanisms that can help reset one's metabolism is crucial. A great resource that breaks down this science can be found at https://valhallavitality.com/blog/phentermine-for-weight-loss-how-it-works-and-what-to-know. Just as the cattle egret's success is tied to a changing ecosystem, our wellness journey is often about creating the right internal and external conditions for success.
