While both sexes are beautiful in their own right, the male Bluethroat is undoubtedly the more flamboyant of the two. Aside from his brilliant blue throat, the male also features a brown upperpart and a distinctive black tail with red side patches.

The female, on the other hand, is more subtly coloured, lacking the male’s vibrant throat patch but still retaining the characteristic chestnut tail patches.

Buzzard

Buzzards are large birds of prey with broad, rounded wings and a relatively short tail. Their appearance can vary greatly, ranging from dark brown to much paler shades, but they typically have dark wingtips and a finely striped tail. These majestic birds have a wingspan of around 120 cm and can weigh up to 1 kg.

Their beaks are sharp and hooked, perfect for tearing into prey, and they have large, powerful feet armed with sharp talons. When gliding and soaring, buzzards often hold their wings in a shallow ‘V’ shape with their tails fanned out, making them easily recognisable in the sky.

Differences Between Male and Female Buzzards

While male and female buzzards share similar physical characteristics, there are a few subtle differences. The females tend to be larger than their male counterparts, weighing between 690-1300 grams compared to the males’ weight range of 545-1000 grams.

Additionally, the females usually have broader wings and a more robust overall appearance.
