Looking for Cliffs under the AZ Falls

It had been a few weeks since visiting my cozy little work patch, so this past week I returned with a specific goal in mind. Having scoped out most of the likely species for this little site, last time here I made specific and successful efforts for Red-naped Sapsucker. This time around I was pursuing a more mobile quarry. I had a single Cliff Swallow back in February, flying around where the canal falls drop down several dozen feet to continue on their westward course. This was a very early sighting for Swallows, and I didn't see that bird upon further visits but it keyed me in to the possibility that in a month or two, they might take up nesting under the Arizona Falls Bridge. Cliff Swallows nest colonially under bridges near water, and are in that sense predictable to find. However, these elevated colonies and the subsequent shade that comes with them means that photographing these birds satisfactorily is a challenge.
Best of all, trying to find the Cliff Swallows at AZ Falls would let me revisit my favorite sign/water fountain placement situation maybe ever.


All of the winterfowl, even the Ring-necked Ducks, in this strip of water are gone, but Cormorant numbers were up. They're mostly Neotropics, but Rhinoceros Cormorant (front) and Headless Cormorant (back) also turn up this time of year. 


The main advantage vis-a-vis Swallowing is that the AZ Falls has a walkway and adjacent slope right next to the elevated plane at which the Swallows are building their muddy manors. This means that without rope ladders or cherry-picker trucks, eye-level viewing is somewhat possible.


With a small amount of trepidation and a certain amount of balance and control, positioning oneself on the dirt and cement slope seen on the left of the picture above allows for fantastic, eye-level views of the busy birds, even if the problem of photographing in the shade can't entirely be avoided.


And as for the Swallows themselves...they couldn't care less. Joggers and cyclists are often passing by on the walkway above their nesting site, and my increased attention did not deter them in any way. Clinging to vertical walls and building a house entirely out of mud and spit requires plenty of concentration, and worrying about the clearly out-of-its-element biped nearby is not high on their priority list.


It was a real treat to watch them working up close. One Swallow would often stay in the nest, molding  the inside no doubt and handling the decoration.  It would then emerge, apparently, to give direction to its partner, who would make the frequent trips down to collect more mud. Have we not all experienced this dynamic, in some sense or another, on a moving day?



And as a further point of relating and sympathizing, Swallows seem to lose patience too during these onerous exercises. Or maybe Cliffs just have a grumpier disposition than cavity-nesting Violet Greens, who find most of their domestic organizing done for them.  


It is interesting also to observe these groups of swallows and compare them to other colony birds. European Starling flocks and Blackbirds fly together and seem similarly sociable, but with the impressive Starling flocks, a sort of a common collective mind seems to pervade the group's movements (even though this likely isn't the case, they just operate, necessarily, under stricter rules that come with being in a larger group). With the gregarious Cliff Swallows, the community is central to everything the birds do--there are seldom any outliers or loners, any separate nests or pariahs. These Swallows are even known to move their eggs from one nest to another if a clutch fails or its own nest is deemed inadequate. 


Swallow crushing is not the easiest of pursuits, but if you can't bring Mohammed to the mountain...then find a way to get up the side of the mountain, lean over some railing, get a bit dusty, and take a few pictures. Everybody's happy.

  1. Nice, dude. I took some Cliff Swallow shots a couple days ago, but I'm not sure I want to post them now, in comparison with this.

      Me. I am. You're still winning by a lot.

  2. Really nice closeup shots of this species! I've yet to see one this year. Hopefully soon!

  3. I've only tried to photograph this species once. But now that you've set the bar so high, I think I'm going to throw my hands up (and my camera) and be done trying. Seriously, these are outstanding shots.

    1. Yes! Look on them and despair!

      Nah I'm kidding of course but thanks for stopping by Josh.
      Next time you're in town...

  4. Great stuff, I love this series! Including the first photo with the swallow's shadow against the concrete. The birds are so expressive.

    I actually tried, for the first time ever, to photograph Cliff Swallows yesterday. Mostly because I was done birding and wanted to stretch out my observation to an hour so it would count in eBird's April challenge. I got one perfect photo, except that it was grossly out of focus. Ended the day with a single keepable photo, of a rough-wing twisted halfway upside-down in midair...

    1. Thanks Lauren.
      I'm looking forward to the return of BASW.

      twisted halfway upside-down midair? Sounds about right : )
