Bird photography at very high ISO

Camera settings for a bird in the bush

My new camera (Canon EOS 7D Mark II) has much better autofocus and ISO range than my previous Canon Digital Rebel XTi (bought in 2006). I've mentioned before that the XTi never had enough light with my 100-400mm zoom lens to use ISO 100, and that ISO 1600 was so grainy (digital noise--especially in shadows) I never used it. So I customarily set the ISO at 400 and aperture at f/7.1 and left it there, letting the camera choose the shutter speed.

On the other hand, the 7D Mark II has infinite ISO. Okay, so it's not infinite, but rather than 1600 it goes to 16000! And it even goes beyond that with special settings that I don't know why you'd use unless taking really grainy photos in near blackness.

I have learned to shoot Manual mode recently and often shoot Manual with Auto-ISO, at 1/1250 sec, f/7.1 @ 400mm as a default "birding" setting, as long as light is sufficient. For more active or flying birds a shutter from 1/2000 to 1/4000 sec stops motion as light permits.

However, when shooting "birds in the bush," hopping from sun to shade or backlit by bright skies, I use different settings.

Autofocus

There are a huge number of Autofocus settings on my camera. But for getting pinpoint focus through the branches on the face or even the eye, I use the Spot AF setting. It is smaller than the default single Autofocus point. I use this setting nearly always. Some of the other AF point selection modes are theoretically "better" for focusing, but I haven't found it to be so, at least on my present lens, which is the old Canon 100-400mm f/4.5-5.6 L IS. This lens is a bit soft in focus. The new lens in this series is supposedly much sharper. But as long as my present lens works I cannot afford to upgrade. Now that I can take 10 frames per second I am able to get some sharper, some fuzzier, in a burst.

Metering

For general bird photography the Evaluative Metering mode is ideal. The Evaluative mode takes into account the entire frame but is weighted more to the center. In RAW you can adjust the color temperature and restore the warm sunny tones you observed. So you don't mess with white balance in the field when shooting RAW.

In recent weeks, however, I've been shooting warblers in the trees against the backlit skies or in dense bushes under a cloudy marine layer and in shade. Jumping from over-bright to over-dark is very difficult--especially if you're chasing warblers through the foliage. If your subject bird takes up at least 15% of the frame width then you can use Spot Metering. In this case your bird is exposed properly even if the background sky is blown out, or the background shadows go to black. It's tricky though, especially for black-and-white birds, or if the bird isn't quite large enough so that you hit part of the bird and part of the background. So frame-to-frame shots may all be exposed slightly differently, depending upon how steadily you hold the focus on the exact spot on the bird. I would not use this Spot Metering mode on a pelagic trip, for instance, where the bird is too small in frame and there the bouncing of the boat, waves, and flying of the bird means that I can't hold steady.

So, I am still shooting Manual with the shutter speeds and aperture that allows me to get good photos with Auto-ISO. Shoot green grass in the open to give you an idea of proper Manual mode shutter, aperture, and ISO settings. Then set shutter and aperture as the green grass would indicate. Set Auto-ISO. Set Spot AF and Spot Metering.

This won't make artistic photographs. But it will give you properly exposed birds for documentation photos, even if the noise is severe. Noise can be smoothed when rendering your RAW files.

The photos below discuss shots of birds on September 16 and 21 of 2018 at Buddy Todd Park in Oceanside, California.

Hutton's Vireo in deep shade. 1/1250 sec, f/7.1 @400mm, ISO 10000.

It's grainy, but still usable.

Red-eyed Vireo against bright sky. 1/1250 sec, f/7.1 @400mm, ISO 2500. 

Evaluative metering would have turned the sky gray and the bird very dark.

Black Phoebe and background in nice even light. 1/800 sec, f/7.1 @400mm, ISO 500.

Evaluative metering would have worked "better" but this came out perfect with Spot metering.

Townsend's Warbler in deep shade. 1/400 sec, f/5.6 @400mm, ISO 16000.

This is as shady a condition as one could obtain a sharply focused bird with my image stabilized lens.

Nuttall's Woodpecker strongly backlit. 1/640 sec, f/5.6 @400mm, ISO 2000.

If Evaluative metering had been used the sky would have been gray and the bird and tree trunk black.

Western Tanager in front of deep shadows. 1/1250 sec, f/5.6 @400mm, ISO 4000.

If Evaluative metering had been used the yellow parts of the bird would have been blown out.

Allen's Hummingbird in shade. 1/1250 sec, f/7.1 @400mm, ISO 8000.

Evaluative mode would have turned the bird dark to compensate for some foliage in the light (cropped out).

With my previous camera only the phoebe had enough light to take a shot! While many of the "high ISO" shots aren't all that great, they are still sufficiently acceptable for documentation photos.

Photogenic Western Bluebirds at Buddy Todd Park

Close Bluebirds in the morning sun are always a joy to photograph.

Here are two pair of photos of Western Bluebirds that are more artistic than many of my shots.

The first pair of photos show a male Western Bluebird in a tree with reddish leaves--perhaps a plum tree, but perhaps something totally different. Ornamental trees in San Diego can be native to any other part of the planet. I thought the contrasting color of the wine red leaves against the dark green background was nice, and love that the background of more distant trees was pleasingly out-of-focus. the little branch up the breast detracts a bit, but perhaps not too much.

1/800 sec, f/5.6 @400mm, ISO 160.

The second set of bluebird photos came from a few minutes later. One is cropped more closely than the other. The background is similar to the first set of photos. So is the angle of the light. For all I know it might have been the same bird in the same tree as the first set!

Mountain Chickadees in Oceanside

One of the surprises I had moving from Oregon to San Diego was hearing Mountain Chickadees in the palm trees. Of course, they are quite rare away from the highest mountain conifers... except in the North County from Escondido to Oceanside, where they are merely fairly rare residents, not "quite rare." And they are more often found in ornamental pine trees planted in town rather than palm trees. But here are two photos of birds in palm trees in Oceanside.

Mountain Chickadee in palm tree. Oceanside, California. September 16, 2018.

I've recorded Mountain Chickadees 122 times in San Diego County from November 2013. Of these, 63--just over 50%--have been in the lowland towns away from the typical mountain habitat. Most have been near my residences--heard while outside doing other things. I've detected them in Escondido, San Marcos, Fallbrook, and Oceanside, all in the NW corner of San Diego County. I've found them in every month of the year, more often in March and April when they are singing more frequently, and August and September (Perhaps when some may be moving out of the mountains?).

So, 63 "backyard" birds in 5 years. That is not really all that rare, after all, is it?

Rare bird: Red-eyed Vireo

Fall migration continues strong through September in southern California. As I explained recently, nocturnal migrants heading for Mexico may find a point of land sticking out in the ocean as a refuge at dawn. Other birds, flying all night, choose irrigated greenery, feeding on insects in tree-tops first lit by the rising sun. That mean parks on the tops of hills near the coast are often prime places to find lots of migrant birds.

Thus, Buddy Todd Park, on the top of a hill in Oceanside, has been quite productive at delivering exciting migrants that are rather rare in southern California. A couple of weeks in spring and a few weeks in fall are your only chance to see many species of migrant birds that may breed in northern forests and winter in the lowlands of Mexico. Buddy Todd isn't nearly as productive as Point Loma, but it is much closer to my home in San Diego's North County region.

Recently I arrived at Buddy Todd Park at the same time as Tito Gonzales. We walked around together for a while and gradually split up. We exchanged numbers to text, in case we found anything interesting. I took many photos of regular migrants and residents. I was actually back at the car ready to be done for the morning when I got a text from Tito. He had found a Red-eyed Vireo on the other side of the playground.

Red-eyed Vireos nest in hardwood forests across southern Canada and the eastern United States, but not in most of the West and Southwest. They have been fairly regular migrants through southern California, but perhaps not found as frequently in recent years as in the 1980's and 90's.

The bird had disappeared soon after Tito found it. It took a good while to relocate the sluggishly moving bird in a dense California pepper tree (Peruvian peppertree Schinus molle). And it wouldn't come out, so I sat under the tree on the grass and shot up against the strongly backlit sky. Thus these photos are less than ideal. Nevertheless, you can clearly see the diagnostic black lateral crown stripe that separates the white eyebrow from the pale gray crown. The eye is more brownish than red, indicating an immature bird perhaps only 3 months old.

Anyway, this was my first Red-eyed Vireo for California, and my first Red-eyed Vireo in over a dozen years. So I was very happy to refind it. And many other people came to see this bird after Tito got the message out.

Bath time with a White-breasted Nuthatch

White-breasted Nuthatches are common enough in interior oak woodlands and also in the pines that top the highest peaks in San Diego County. Nearer to the coast, however, they are much less common. I found several at Buddy Todd Park in Oceanside recently.

Usually they are constantly on the move crawling up and around tree trunks, in and out of shade and foliage. So getting good photos is not easy. But I found one out taking a bath on a sidewalk irrigation puddle. Here are two decent photos to share.
