Baltimore Orioles

Baltimore Orioles are one of bird-watching most prized songbirds, beloved for their song and bright, distinctive coloring. Baltimore Orioles are very common throughout New Jersey, though they are less likely to be seen in the Pine Barrens. Besides those birds that decide to reside in the Garden State all summer, the best times to see these beauties is actually in the spring and fall, when their numbers increase with the migration. The earliest sightings are usually mid-April. Typically they have migrated completely by late September, heading south to winter in the much warmer climates provided by Central and South America.

Baltimore Orioles are easy to spot and even easier to identify. As one of the northeast’s only orange birds, they are difficult to confuse with anything else. Both sexes are the same size, growing to be between seven and eight inches. However, it is only in size that the sexes are similar. The male Baltimore Oriole displays his orange coloring on his belly, across his shoulders and the underside of his tail. Though limited to certain areas, the orange appears brighter and more startling because it contrasts so strongly with his black head, back and wings. He has white wing bars and white flashes can be seen on this wings while he is in flight.

The female Baltimore Oriole has more orange plumage than the male, with an orange head. The tint of her orange feathers is slightly duller than her male counterpart, but only just. Only her wings and back are gray-black, or olive with white wing bars. She looks very similar to female Orchard Orioles or Hooded Orioles, but their plumage is more yellow than orange. If you have time to study them beyond the dazzle of their feathers, you will notice that the Baltimore Orioles have dark, penetrating eyes, a pointed gray bill and gray-black legs and feet.

Baltimore Orioles like to live on the edge of deciduous woodlands, and don’t mind being close to human habitation. They choose to build the nests high up in the tallest trees. Their nests are very interesting, being a sock-like sack that dangles down from a branch. They make it by weaving plant fibers together.

Once the nest is ready for their four or five blue eggs, the male leaves the female to incubate for twelve to fourteen days. Once the eggs hatch, he returns and they feed the new babies together for the next two weeks. As they grow, the juveniles will take on the plumage of a female, with the males not growing their adult plumage until they are in the second or third year.

A Baltimore Oriole’s diet is widely varied. They eat insects, but also like fruit and nectar. They will come to feeders for fruit, nectar and suet. Jam/jelly feeders is another favorite. They definitely have a sweet tooth. As they grow, the adults will not be shy about bringing their fledglings along to feeders, so as the summer progresses you might have an opportunity to see the whole family.

Painted Turtles

Today I want to take a little time to focus on a non-feathered inhabitant of New Jersey’s many nature parks, the Painted Turtle. A common northeastern reptile, I encounter Painted Turtles on many of my excursions, as I am sure do most nature lovers. I am very fond of these colorful little guys, with their often grumpy faces and knowing eyes.

The Painted Turtle is one of the most common turtles in North America, being found from the Atlantic to the Pacific. In New Jersey they are most active between April and September. Because of their wide range, there are actually four types of painted turtles: Eastern, Midland, Western, and Southern. Therefore, the turtles that I see here in New Jersey are most likely of the Eastern variety.

As its name implies, the Painted Turtle is very colorful. Its black or dark brown skin is striped with a series of horizontal red and yellow streaks. The stripes reappear on the turtle’s butt. Its similarly dark brown shell is edged in red flashes. All together these markings make the Painted Turtle very recognizable. If you are on the lookout for a Painted Turtle, don’t be looking for anything too big. They typically don’t grow larger than seven inches. Generally the females do grow larger than the males, but not to the degree that you could identify the genders by size alone. Usually, they will not grow beyond the means of their habitat, basing their size on the available food in the area.

Known as a “pond turtle,” Painted Turtles adapt to almost any body of still water. They are commonly found in ponds, marshes, beaver ponds and slow moving streams, however they prefer bodies of water with muddy bottoms and vegetation. The presence of water is key, as they are very active swimmers. Besides swimming, their other favorite activity is basking in the sun. If you approach a pond quietly, you are almost guaranteed to see at least one basking turtle, with its neck and back legs outstretched to their limits, balancing on a rock or log and soaking up the rays. But be ready for the “kerplunk” that inevitably follows. The minute the turtle senses you presence it will pop back into the water for safety.

Breeding season for the Painted Turtle begins in early spring. At that time males can be observed leaving their ponds and habitats and sometimes crossing a lot of terrain, in search of a female. Once they have mated, the female nests between May and June. She will typically build her nest within a few yards of the body of water she calls home, but some females have been known to travel greater distances to find the ideal nesting area.

Painted Turtles can lay anywhere between two and eight eggs, however five or six is typical. Once laid, the eggs will incubate for up to eighty days, usually hatching in late summer. The hatchlings, who look like miniature adults, will remain in the nest until the following spring. And who would blame them? It is a dangerous world for a little turtle. Painted Turtle nests are commonly raided by skunks, raccoons, foxes, snakes and other small mammals that eat the eggs. Once hatched, the juveniles are still in danger. They have been known to be eaten by large fish, snapping turtles, herons, crows and raccoons. Humans also cause some casualties both with vehicles and lawn mowers.

The young Painted Turtle’s best strategy for survival is to get bigger, and those that survive the early days do just that. While adult Painted Turtles are omnivores and eat a combination of meat and vegetation, the young Painted Turtles’ diet is a concentration of meat protein. With the nutrients present in the meat, they are able to double in size in their first year out of the nest. Once they grow larger, their diet will become more varied. Adult turtles eat beetles and other bugs/insects, algae and small fish. If they survive their first few years, Painted Turtles can be in for a long life. They have been known to live between twenty and forty years in the wild. They reach sexual maturity and begin breeding around ten years old.

American Goldfinch

Found throughout the state of New Jersey in great numbers, it is little wonder that the American Goldfinch was officially declared the New Jersey state bird on June 27, 1935. Not only are they found around the state, many of the Goldfinch stay around all winter. However, in northern New Jersey we usually only see them in spring and summer as many of the state’s population migrate further south with the cold weather, in search of larger sources of food. At one time the population was noticed to decline as the House Sparrow population increased, but today the numbers have stabilized and the species is not considered under threat.

At five inches, the American Goldfinch is an inch smaller than most sparrows. But what it lacks in size, it makes up for in color. We all know this iconic bright yellow bird. The male has a black patch at the front of his head, as well as black wings and a tail. The wings have small bars of white, and a small patch of white is sometimes visible on its belly, right where the tail connects to its body. The female is just duller in color all around. The classic example of bird species where the vibrant male plumage is in contrast with a female of mellower coloring. The female’s yellow is just duller, almost grayer than her male counterpart. The black and white of her wings is also a bit more drab and she lacks the black on her head.

The male American Goldfinch does experience one of natures more drastic molts. After the conclusion of the mating season, the males lose their bright luster and appear much more muted, almost indistinguishable from the females. He does not even retain his black forehead plumage. His transformation in early spring, back into the brighter version of himself can sometimes seem even more extreme. During this process the males often look ill or strange, with patches or tufts of white scattered among the brighter yellow feathers.

The American Goldfinch eat a wide variety of seeds, as well as some berries, flowers and the occasional insect. They will visit seed feeders, but if you want to be sure that they find you, you can fill a feeder with exclusively Nyjer seeds. Nyjer attracts finches the same way that catnip calls to cats. It really works. Nyjer seeds come from the African yellow daisy, and they are so appealing to the finches because of their high oil content. Unfortunately, the Nyjer seeds are more expensive than the average backyard bird mix.

If you do succeed to attract New Jersey’s mascot to your feeders, be prepared for some of the most wimpy behavior you have ever seen. Goldfinch are not just flighty or shy, they are the most hesitant bird I have even seen. Often coming to my yard in groups of three to seven, they will slowly hop from branch to lower branch, calling to each other in their high-pitched squeaks. I swear the squeaks have a questioning inflection. “Is it safe?” “Is it safe?” They leap frog their way down the trees until the group finally convinces one bird (often a female, which I find interesting) to go the distance and land on the feeder. Once the guinea pig passes the test, the others will tentatively make their way over, often one at a time. But the slightest motion from an observer, or another bird, and they are all off like a shot, back up to the top of the tree, to start the process all over again.

If you are looking for the American Goldfinch beyond your own backyard, you can frequently find them in fields with high grass and weeds. They are also fond of open woodland. Gardens with lots of sunflower type plants are another good spot to look. Outside of the breeding season, they can be found in groups of up to twenty.

The American Goldfinch is known to be late to nest, waiting until late August or sometimes even in early September before they nest. The females usually build their cup-shaped nest in the fork of a tree branch and, like the hummingbird, they use spider silk and caterpillar webbing on the outside of the nest as binding. Due to their late start, the American Goldfinch only have one brood. Each brood consists of between four to six blue eggs, which the female incubates. The male will return to the nest periodically to feed her, but she sometimes has to call him and beg for him to return. Once the eggs hatch, the male assists with the feeding of the young. From year to year they will select different mates and are not monogamous.

Trustom Pond National Wildlife Refuge

Exactly a year about, I found myself camping with a friend in Rhode Island. We were staying just over the Connecticut border in Burlingame State Campground. It was a lovely spot and great for outdoor activities, with the campsite right on a small lake. One day we decided to leave the campground for a hike at the nearby Trustom Pond National Wildlife Refuge. The refuge, which encompasses 787 acres, is home to roughly three hundred bird species, over forty mammal species and twenty reptile and amphibians. The habitats included within the borders of the refuge include fields, shrublands, woodlands, fresh and saltwater ponds and sandy beaches and dunes. What makes it extra special is that this refuge is the only undeveloped coastal salt pond in the whole state of Rhode Island. For we two-legged mammals, the refuge also provides roughly three miles of nature trails, including two observation platforms.

When we arrived at the refuge it was late morning. The day was already very hot. As we set out on the trail, it was amazing how green everything appeared. As we got closer to the water, many of the trees grew in curved and sprawling directions rather than heading straight up to the sky. The appearance of dry stone walls here and there added to one’s impression of a mystical, otherworldly atmosphere. You felt that seeing a fairy or a leprechaun wouldn’t be that out of place in these woods.

When we did spot some movement in the trees, it turned out not to be a fairy after all. Rather a lone Cedar Waxwing was hoping around the branches, either snacking or collecting some material for its nest. Always easy to identify with its distinct body type, black mask and yellow tail tip, this Cedar Waxwing was so busy, it made no attempt to hide from us.

Further down the trail we saw another flash of movement, this time a brighter, yellow flash. A Yellow Warbler perched on a branch just long enough for us to get a decent look at it and snap a few photos before it was off again, a bundle of energy and activity.

At this point the land around the trail became noticeably narrower, as we approached the peninsula where the Osprey Point observation platform was located. We noticed that the water had a foggy haze over it, helping to further enhance that mystical atmosphere we had begun to sense earlier. Unfortunately it also negatively affected our visibility.

Once up on the wooden observation platform we were confronted by a rather large bush or shrub, which had used the man-made platform as a trellis to allow it to reach even further into the air, toward the sun. But while the vegetation obscured our view even more, it was itself a haven for many of the smaller birds that love that kind of covering. A Song Sparrow was the first to show himself to us, belting out his song with great enthusiasm. Rustling in another part of the bush revealed a male Common Yellowthroat who came into view only long enough for me to begin lifting my camera before he hurried back into the network of vines and leaves, away from sight. However, after a few minutes, a much less jumpy female Common Yellowthroat came into view. She was much less skiddish than her male counterpart and I was able to get some very clear photos of her as she gleamed among the flowers.

Extending our gaze beyond the vegetation, we were able to spot one Double-Crested Cormorant, fishing in the brackish water. Additional movement on the water’s surface caught our eyes. But what we saw was definitely not a bird. It took us a few minutes of guessing before it came close enough for us to realize we were looking at an otter. Whether it was a river or sea otter is difficult to tell, but it was probably a river otter, as this was a fresh water pond. It turned out to be one of several that we saw when we started looking closer. They appeared to be bringing building materials from deeper water in toward shore, possibly to build a nest. They were much bigger than I expected.

After watching the otters for quite a long time, we headed back on the trail and went to the second observation platform, Otter Point. There the fog was just as thick, but the vegetation was a bit thinner. We watched a pair of Canada Geese make their way slowly across the water, when we saw a large bird fly in and land on the naked branch of a tree across the water from us. After a few minutes the Osprey flew off, caught a fish and then returned to the same perch and began to eat it. The irony was not lost on us that we saw otters at Osprey Point and an Osprey at Otter Point.

The Osprey’s meal reminded us that we were ready for lunch ourselves, so we started to head back along the trail. Emerging from the woods, the trail skirts the edges of a large, open grass field. On one of the only trees in the area, a gnarly looking fruit tree, we noticed a Tree Swallow. He was most likely resting after having flown repeatedly over the field gathering the many insects that were hovering in the thick and humid air.

Before reaching the car, the trail took us alongside the Farm Pond, a scenic little body of water, covered in vegetation. Getting closer to look for fish or turtles, we spotted several frogs floating among the lily pads. Most likely American Bullfrogs, these frogs floated below the water’s surface, allowing only their eyes, and sometime the tips of their noses to emerge above. Having spotted several frogs, we once again headed for the car. We didn’t make if far before we were distracted by the rustling of leaves high up in a maple tree on the opposite shore. A quick look through my lens revealed a rather noisy female Baltimore Oriole, picking at something, possibly some tasty insects or sap. Having seen her eating confirmed that we were past ready for lunch, and we practically marched back to the car to go out in search of our own sustenance.
