HOW DO MERLINS DIFFER FROM AMERICAN KESTRELS (AMKE)?

• Slightly larger and notably heavier (thus having more speed and endurance in flight)
• Different colouring, e.g. lacking the indicative reddish-browns of the AMKE
• Distinctive tail-barring as against black ends to the tail feathers with a white fringe
• Unlike the AMKE they don’t hover, but close in directly on the small birds that are the main prey, often flying very low to surprise the victim.

For comparison: Merlin in  South Abaco, American kestrel at Sandy Point

 SO JUST HOW FIERCE ARE MERLINS?

Formidable! If you are a small or even medium-sized bird, you need to keep your wits about you. Merlins are largely ‘omni-habitat’ within their range, which includes open country, shrubland, light forest, and grasslands. They are fast, agile and strong. They can fly high, at medium height or at ground level, and are expert in surprise attack and rapid pursuit of prey. If you are a large bird of prey – a red-tailed hawk, perhaps – they may attack you with ferocity. They may not actually be trying to nail you, but to get you out of their territory and their catchment area.

Most of a merlin’s prey is taken in flight, and their speciality is ‘tail-chasing’ terrified birds. Breeding pairs may hunt cooperatively, with one bird flushing prey from cover into the open for its mate to… well, you get the picture – they are clever too. They may even pursue birds that have been flushed out by another bird of prey in the vicinity.

MERLINS AND PHOTOGRAPHERS

This is a slightly fraught relationship, because Merlins do not always pose as one might wish. Sometimes they are hard to see, being fairly well camouflaged unless they choose to ‘go out on a limb’. 

And sometimes they don’t play by the rules relating to light and focus, making a clear shot difficult

FALCONRY AND MEDIEVAL HISTORY

Merlins were popular birds in medieval English falconry, and according to the 1486 Boke of Seynt Albans, the ‘Marlyon’ was considered the appropriate hunting bird for a lady. This book contained an essay on hunting attributed to Dame Juliana Berners, the prioress of a Priory near St Albans, who, game lady that she must have been, also contributed to one of the earliest treatises on fishing, ‘Fysshynge wyth an Angle‘ (hence, angling).

FURTHER HISTORICAL DIGRESSION (feel free to skip to final para)

While reading up further about Dame Juliana, I came across (wiki-tnx) a wonderful ranking for birds of prey matched to status that I hadn’t encountered before. Here’s the list, from Emperor to Knave / Servant. A Tercel was / is a male falcon, especially a Peregrine or Gyrfalcon. A Musket is a sparrowhawk. 

The Boke of Seynt Albans also contains list of collective nouns for animals and birds, many familiar today such as “gaggle of geese”. There are also humorous collective nouns for different professions, such as a “diligence of messengers”, a “melody of harpers”, a “blast of hunters”, “a subtlety of sergeants”, and a “superfluity of nuns”…

Merlins are still trained for hunting smaller birds; and because of their speed and agility they are used in falconry displays. Despite changing habitat, and a perceptible dip in population from the use of pesticides now banned (such as DDT), the Merlin seems to be holding its own very well 5 centuries after the Boke was written.
