Hungry hairy herons and their caring parents

A little over a week ago, fellow photographer Mary posted a wonderful photo of young green herons (Butorides virescens) perched in a row awaiting their parents. They still had very fuzzy hairdos, reminding me a bit of a row of Albert Einsteins. About 4 days later, I drove to the pond in a senior citizen residential community to see them and they had already lost most of – but not all – the fuzz atop their heads. That didn’t matter though because it was a real pleasure watching them for a while.

 

Friend Lucretia had accompanied me and we were lucky enough to park right near the end of the pond where the sibling group was parked. Only one was out on a limb when we arrived; the three brothers/sisters were in hiding in the thick shrubs bordering the pond.

The bold juvenile may have been the eldest of the quartet as s/he seemed to have lost the most fuzzy feathers.

 

 

S/he groomed, looked around and then yawned hugely – making me think of how I often want to react to much of the news that is shown in the media these days. This was followed by what looked like a smile and happy reaction, which is how I often feel when out taking one of my nature walks!

 

After a while, a couple of No. 1’s siblings began moving around in the brush, eventually coming out into the open.

In the meantime, No. 1 took the time to defecate; gotta take care of those body functions! (It’s interesting that birds all have white poop. The fecal sacs that songbirds take out of nests are white; this bird’s stream of feces was white. Why? Here’s a tidbit of information you might not know: Birds’ bodies do not produce urine as mammals do. Rather, they excrete nitrogen wastes as uric acid in the form of a white paste.)

Another sibling did some preening.

 

 

 

As we walked around the end of the pond, it turned out that Mama was taking a rest there. (I really can’t tell the male from the female adult but for convenience’s sake just identified her as the mother since she was close by.)

 

After a time, Mama took off and ended up in a perch on the underside of a small dock. It made me wonder if that was a good place to fish because the water might be a bit cooler and perhaps fish were schooling there. A good number of turtles were also swimming about there – perhaps the shady area was just a nice break from the sun-warmed water.

 

 

 

While Mama scanned the deeps, a nice song sparrow (Melospiza melodia) and a beautiful Eastern bluebird (Sialia sialis) entertained us with song.

Brown-headed nuthatches, a brown thrasher, and a downy woodpecker (Picoides pubescens) were among the other birds flitting about the trees and shrubs bordering the pond.

While adult green herons sometimes use tools to fish – using twigs or insects as bait – Papa heron was just standing patiently at the other end of the pond, watching the water intently. He suddenly plunged and ingested a small fish, using what one ornithologist called a “bill lunge”, in which the bird keeps it feet in place but stretches its body forward to spear prey with its long bill. Apparently, green herons can also catch prey by hanging upside down from their perches over water.

 

We wondered if he was eating the fish himself or collecting a gullet-full of food for his offspring. Herons namely feed their young by regurgitating previously-swallowed food.

As we continued our walk around the pond, we came upon a great blue heron (Ardea herodias) who had some good luck in getting a meal.

When we arrived back at the spot where the young herons were hanging out, we saw a beautiful gray catbird (Dumetella carolinensis) snag a meal of its own.

One of the young herons was in the water, apparently practicing fishing behavior. S/he caught something but then let it go.

Then Mama suddenly flew in; the foursome greeted her excitedly and Lucretia saw her regurgitate a meal onto the grass. (Unfortunately, this happened behind a shrub that I could not see around so I missed that behavior.) When I had moved over to see the young ones, they had already gulped down whatever food there was and were engaged in vigorous behavior to convince Mama to repeat what she had just done.

 

This gave a fairly good view of the group. One still had a very pink bill while others were getting more yellowish bills on the way to getting dark beaks.

Mama flew off to a tree and apparently settled in for another food-gathering exercise, while one of her young ones called piteously.

 

After a couple hours, we decided it was time to drive back to our own areas of residence, but it was bittersweet having to leave the group of four behind. But they certainly provided us with an entertaining morning, even if that was not their intention! We hope they will grow up with no threats from predators and be able to repeat the process with broods of their own one day. 😊

Surprise gifts from Mother Nature in 2018 – part 1: birds

On the last day of January 2019, I thought it would still be ok to post a couple blogs on some surprises I encountered the past year. Almost always when I go out on nature walks, I encounter something new – a species of wildlife or plant that I have not seen before or an interaction between species not previously observed. So, I wanted to share a few of those delightful surprises from 2018. In this blog, I focus on birds; in the next part, other kinds of wildlife will be featured.

As I mentioned in a previous blog, my own front yard was the scene of my biggest surprise last year when a snowstorm brought feeder visitors whom I had never seen before and who rarely come to the state where I live. The evening grosbeaks were just stunning.

 

They were not the only grosbeaks who treated me with their beauty, however. I’ve had rose-breasted grosbeaks (Pheucticus ludovicianus) visit the feeders before, but they still always elicit my appreciation with their bright colors.

 

In late October, an osprey (Pandion haliaetus) made me stop for a photo as the other birds of its species had already gone south for the winter. The bird was perched on a branch extended over a pond and had to unfortunately contend with a persistent crow that was harassing it. After some time, the sea eagle finally took off with the crow in pursuit – it seemed that the osprey might have injured its wing and perhaps that accounted for a delayed departure to warmer climes.

  

Although the pursuit photos are not high-quality, you can see a gap in the osprey’s wing and perhaps it was waiting for healing before it undertook a very long journey.

 

On another day, I was near a wetland when an unexpected visitor flew onto a branch above me. Green herons (Butorides virescens) usually keep their distance from me; I regretted that it was overcast and the lighting was not wonderful for my close-up portrait of this colorful immature bird.

 

A more muted bird, but lovely nonetheless, is the Northern mockingbird (Mimus polyglottus). When I saw this individual in late December, I was thinking that it must be difficult for them to find food as the vegetation shrivels and insects are in hiding. At that moment, the bird dropped to the ground and was foraging – coming up with a bug to prove that they still could find sustenance in the cold temperatures!

  

The mockingbirds are often solitary except for breeding season. Some people complain that they are aggressive towards other birds at their feeders but those in my yard are not that way at all. They share space at feeders and don’t chase anyone else away. When it is mating and nesting time, however, they can become quite territorial and are very protective of their nests. This seasonal “grumpiness” was brought home to me one day along a country road when I witnessed a pair of mockingbirds driving a third bird – rival? Intruder? – away from their roosting spot.

When large flocks of gulls and double-crested cormorants (Phalacrocorax auratus) visited a small local lake because of a shad die-off, I had the chance to watch them for a while. One day, it was interesting to observe how one cormorant wanted to jump up on a floating platform, but another bird didn’t want him/her there. They faced off with open beaks – the bird wanting to get out of the water won.

 

 

It’s always interesting to me to watch birds as they forage for sustenance. When I think of woodpeckers, my thoughts immediately turn to nuts and insects, which I think of as their staple diets. So it was a surprise to me to see this red-bellied woodpecker (Melanerpes carolinus) dining at length one day on nice ripe persimmons – a bird with a sweet tooth!

 

 

 

Well, I probably shouldn’t say “sweet tooth” but “sweet tongue”. Woodpeckers don’t have teeth but they have exceptionally long tongues that can be wrapped around their brains inside their skulls when not being used to extract insects and other food morsels from crevices.

Another bird that has a long tongue is the great blue heron (Ardea herodius). One day, I came across this bird on its favorite roosting log obviously trying to dislodge something that had gotten stuck – or perhaps something that tasted foul. I hadn’t really seen the species’ tongue before, so the bird gave me some good views.

  

The effort of shaking its head also led it to protect its eye with the nictating membrane.

Because tufted titmice (Baeolophus bicolor) visit my bird feeders daily to get nuts and, to a lesser extent, seeds, I associate them completely with that type of diet. It was that assumption that made me do a double-take when I spotted a titmouse on a walk with a long spaghetti-like object dangling from its beak. It didn’t seem like a grass stalk so when I lifted my camera to look through the zoom lens, I discovered it had a worm snake (Carphophis amoenus amoenus) in its beak – a finding that really did astound me.

 

As I took photos, the bird finally flew further away and unfortunately dropped the reptile when it came close to a creek. I felt a bit guilty, thinking I might have disturbed its meal but after waiting about 5 minutes, the bird suddenly flew up with the snake back in its beak! It obviously really wanted to hang on to that prize!

 

And now on to part 2 of my 2018 surprises – some more reptiles and amphibians, bugs and mammals!
