Not that I'm aware of - just eats storage and battery! That said, with a heavy camera, you're unlikely to keep it firmly on target for much of the burst!
I think what's happening is the long focal length allowing distant shots is giving a much greater depth of being in focus, combined with decent sunlight, and often trees in the full frame that are the right sort of distance way (these are massively cropped down from the full frames). This gives a better chance of the auto-focus getting it right. Also, swallows do have slower glide phases in their flight which can help to get on target. What I was forgetting is to try burst shooting to up my chances.

Reading, UK - today, which rather surprised me to still see a flock of Swallows around. I find them really hard to photo - they notoriously don't land, and fly fast, so this lot of photos is as good as I get.

Yes, there's both buzzards and kites around here - very similar life-styles.

I like how the colours came out, especially as this was a dark bird on a white sky, which is always needs correction when on auto-ISO.

I'm reasonably sure this is a Chiffchaff, though it might be some other sort of warbler, and I was pleased to get such an action shot. (even if a bit obscured) Reading, UK.
Nice shot, but are osprey nests always that rough & ready?
I think it fairly obvious that the first European settlers in North America were far from Ornithologists :)
As you've most likely already seen to find those links, Red-tailed hawks and (what I think of as) a Buzzard share a genus Buteo.
OK, that would be a danger to my wallet!

Just rejoicing in a moderately sharp shadow , and a slightly wistful look - yes, sunlight in Reading, UK!
I'd guess an adult transitioning from breeding plumage.

I decided I was being snobbish by ignoring an obvious flock of "wild" birds in easy reach: in my local town centre - though sadly the light today was not that great.
One of my books lists four broad types, all represented here: Chequered, Rock Dove type, Pied and Ginger.
And look well-nigh identical to the UK Magpie - though the Latin name is different.
A young one from yesterday for contrast:
Happily, Prospect Park often gives a good distance view, so I can see them coming, especially if circling - even so, I often lose focus especially when "close" overhead. There's also the curse of shooting dark subjects against bright sky - my camera's auto settings would have this photo as little more than a silhouette, but happily shooting in RAW allowed a decent recovery.

I didn't actually intend to capture this robin in motion from tree trunk to branch, but this lucky accident amuses me.

Looking back at my old photos from various locations, that "not round pupil" thing in wood pigeons seems more often present than not. I wasn't something I'd looked previously out for.

Or just "Pigeon Post"? Or even "Recreational Route". Anyway, Wood Pigeon, UK, awaiting the best title I can give it.
Really nice to get that angle - I'd guess you were half way up a mountain at the time.
You will be shocked to know even the mother can walk through those bars.
Thanks - thought you'd have to have a huge pixel count otherwise.
Anyway, hoping to walk to a new spot when photoing birds, and not expecting it to flow off, is a mug's game :)

... well, a park fence round a pond, any way.

I like the way you've shown the context in one photo, the bird in the other. Is that just digital zoom or two photos and an optical zoom?
The sparrow was just pure good luck, and a bit of a surprise when I reviewed the photo!
And I suppose to complete it, House Martins from the same group gathering the mud in the harbour

The House Martins were in the process of building this nest from harbour mud, though I think they gave up on it over the coming days. Why the sparrow was interested I do not know!
It is indeed a Canon, and using Canon's DPP4 to correct the over-exposed whites using the RAW format of pictures. I really ought to research it properly, but I'm guessing that different colours (YGB) are reaching over-exposed to different degrees and getting capped. E.g. Blue is very over-exposed, Yellow is a bit over-exposed and Green is only barely over-exposed. Then when I try to bring them back to properly exposed "as one" with the histogram tool or brigtness slider, those caps and degrees are getting messed up, giving a colour balance in a manner that doesn't reflect the original and I get a green tinge.
That, or pay more attention to whites in frame!

Sometimes it takes everything you've got to get those feathers correct!
Young gull, probably either Black-backed or Herring.
