Pond Dramas
Sometimes one can sit at a pond full of birds when there seems to be nothing going on. But if you pay close attention there’s often a host of little dramas playing out right under your nose.

Grebe Running On Top Of The Water
I’ve long wanted a shot of a grebe completely out of the water as it ran across a pond. Two days ago I got it.
Pied-billed Grebes Frantically Protecting Their Fish
Yesterday morning the normally placid Farmington Bay Pied-billed Grebes were in a feeding frenzy and I had a wonderful time photographing the action.
A Coot In Pursuit Of A Grebe’s Fish
Although the American Coot is almost exclusively a herbivore it will occasionally make an exception and eat animal matter. They’re also well-known for food thievery (kleptoparasitism) and two days ago this Pied-billed Grebe nearly became one of its victims.
Pied-billed Grebe Feeding Behavior And An Invasive Species
Yesterday morning the Pied-billed Grebes at Farmington were having a bit of a feeding frenzy and I was able to capture several instances of interesting feeding behavior.
Grebe Running Across A Pond’s Surface To Protect Its Prized Fish
At first glance Pied-billed Grebes may come across as nondescript, bland little birds without much personality but I’ve found the opposite to often be true. When they’re not resting or grooming they’re active, quite vocal and when they’re feeding in groups they’re often aggressive, even pugnacious. Their kleptoparasitic tendencies can be entertaining to watch in the extreme.
Notice the layer of ice at the bottom of the frame – that ice will come into play later in the sequence.
Pied-billed Grebe With Eyes Bigger Than Its Than Stomach
Pied-billed Grebes are both pugnacious and gluttonous and it’s not unusual for them to capture and attempt to swallow prey that is marginally too big to go down the hatch, which can lead to some interesting and amusing behaviors at feeding time..
Pied-billed Grebe On Nest
Yesterday morning I was very surprised to see this active nest so close to the loop road at Bear River Migratory Bird Refuge. Both parents incubate and the sexes are similar so I don’t know if this was the male or the female but the apparent mate of this bird was hanging around in the general vicinity.
The Raven And The Pied-billed Grebe
Last week as I drove along the causeway to Antelope Island just after sunup I came across a Pied-billed Grebe on the shore that was being tormented by a Common Raven. I still don’t fully comprehend what I witnessed.
A Couple Of Interesting Pied-billed Grebe Behaviors
I love watching and photographing these small grebes because their pugnacious behaviors produce some fascinating interactions. They just may be the most aggressive bird species I’ve ever photographed.
A Pied-billed Grebe Attempts To Dismember A Frog
Pied-billed Grebes are opportunistic feeders, taking large crustaceans (especially crayfish), fish, insects and other invertebrates. They also consume a lot of frogs when they’re available. When the prey is too large to swallow whole (frogs and crayfish especially) they grasp the appendages with their beak and shake it vigorously until the limbs break off. I’ve also seen adults tear off bits of the body trunk of frogs to feed to their chicks. This bird is a juvenile, still learning the finer points of consuming prey. This stage of plumage development is referred to as the “stripe-head stage”, for obvious reasons. Adults lose those stripes. The frog it has captured is probably one of the first amphibians the bird has had to deal with without assistance from a parent and that inexperience seemed obvious as the young bird dealt with the frog. I’ve presented all the photos in this series in the order they were taken. As you can see, the young frog hasn’t yet fully metamorphosed into an adult and retains the tadpole tail. The grebe would repeatedly grasp a limb (it tried all 5 of them several times)… and then shake the frog violently in an apparent attempt to tear the appendage off like it has seen its parents do so many times before. Here it’s working on the left front leg. Other times the bird would grasp the body and shake. Hard! At times the grebe would appear to rest and “think” about its…
A Gluttonous Pied-billed Grebe
Pied-billed Grebes are opportunistic feeders so they’re not very fussy about what they eat, but they do seem particularly fond of crayfish, fish and frogs (including tadpoles). Before consuming crayfish and frogs (both are often too large to swallow whole) they rip them apart in an incredibly rapid shaking frenzy that tears off limbs and pieces before they’re swallowed (something I’ve documented here with a frog). They have very strong jaw muscles and before swallowing fish they repeatedly pinch them with their beak, which kills them by damaging their internal organs. Occasionally, when choosing prey, their eyes are bigger than their stomachs – as you’re about to see. (all images are presented in the order that they occurred) All images presented in this post had the following techs: f/6.3, ISO 500, 500 f/4, 1.4 tc, shutter speed ranged from 1/2000 to 1/1250 Last winter, I noticed this grebe just after it surfaced with a fish. A very large fish, at least relative to the size of the bird who must now swallow it. (I’ve never seen one tear a fish into smaller pieces before eating it). As a side-note, I liked the “extra eye” in the reflection at the bottom of the frame. I thought this image would give the viewer a good sense for the size of the fish – especially its width! But the poor bird didn’t have any time at all to get the meal down before other grebes rushed in to try to steal the fish. The competition at times like this is…
Pied-billed Grebe Showing Off A Little
I’ve always thought of Pied-billed Grebes as sort of the Rodney Dangerfields of the bird world because they just “don’t get no respect”. At least they don’t get as much as I think they deserve from bird photographers. They’re plain little brown birds, very common (in fact they’re the most widely distributed grebe species in North America) and often when they’re seen they’re just sitting calmly on the water so many photographers usually ignore them. But if you spend enough time with them it won’t be long till you see that they’re full of personality and interesting behaviors. They’re pugnacious, aggressive and extremely active in bursts. I enjoy the heck out of them. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in While I was watching this bird float effortlessly on the water it began to rouse (ruffle its feathers). Sometimes rousing is a precursor to a wing flap so this time… 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in I was ready when it happened. When grebes do a wing flap they raise their chubby little bodies out of the water. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This one didn’t last long and here the bird is already beginning to settle back onto the water. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in…
Some Recent Shots I Like, Despite Some Flaws
Like every other bird photographer many of the photos I take are not worth keeping. For the first few years I was shooting birds I estimated that I deleted 90% of my images. Now that I’ve become a little more discriminating that number is probably closer to 95%. Birds are incredibly difficult subjects – they’re fast, unpredictable, difficult to approach and generally uncooperative. When I’m culling images after a day in the field most shots fall under two main categories – keepers and garbage. But there’s often a few that are technically lacking for one reason or another but have some unusual or especially interesting feature that makes it difficult for me to trash them. So I don’t. Occasionally I go back through them just for the fun of it. I enjoy them and thought some of you might too so here’s a few from the past month or so. 1/2500, f/7.1, ISO 500 500 f/4, 1.4 tc This one’s from yesterday – a Lark Sparrow that posed and groomed for us for quite a while. Looking through the viewfinder I had no idea there was a second Lark Sparrow in the vicinity and didn’t even notice it flying through the frame until I got home and looked at it on my computer. Mia said that she’d noticed the second bird and that it chased the first bird away when it flew. Anyway, I thought the out-of-focus sparrow to the left was an interesting serendipity. I just wish the two twigs by the head weren’t there. 1/2500, f/7.1, ISO 500 500 f/4, 1.4…
Pied-billed Grebe With A Mouthful
Just a single shot this time. I’m often blown away by the ability of some species to swallow huge prey whole when I have trouble gulping down anything much larger than an aspirin without chewing it first. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc A few months ago I watched and photographed this Pied-billed Grebe for 13 minutes as it tried to get this fish down its gullet. Other grebes attempting to steal the prize didn’t make the process an easy one but eventually the bird was successful. It’s not readily apparent in this shot but the fish was much wider than the head of the grebe. I could hardly believe what I saw… Ron
