Pine siskin vs. American goldfinch video

More and more siskins

It started out as two yesterday morning. Now there are more than 20 pine siskins at my backyard feeding station in Danbury, Conn. That’s often the way it goes with these winter finches: The visits start with a few birds and they multiply and eat the host out of house and home. Not that I’m complaining …

Every perch on the hopper is filled and the rest are on a nearby hopper feeder or on the ground. They are eating Nyjer and sunflower seeds. 

Siskin irruption hits home — finally

After reading about pine siskins being seen throughout New England for several weeks, I woke up this morning to three of them at my feeding station. Pine siskins are one of the winter finches that irrupt from the north into New England and points south in sporadic winters. (Related post may be found here.)

Pine Siskins are often confused with goldfinches because they look fairly similar and prefer Nyjer (or thistle) seeds. Siskins are a bit larger, more sleek, more streaked and have a longer, pointed bill. The heavy streaking, especially on the sides, and yellow wing and tail markings are the best clues to differentiate the species. The male siskins have more prominent yellow markings. 

So today I celebrate that the siskins have arrived. The birds, however, have a very healthy appetite and Nyjer seed is not cheap, so we’ll see how I feel if their numbers multiply. I’m sure I’ll continue to be inspired by their presence. After all, it’s been about 10 years since I was a part of one of their irruptions. I think I can splurge once a decade on them. 

Here is a photo of them with goldfinches. Note the differences in plumage. The goldfinch is on the lower right.

For the Birds: Fox sparrows back in force

Here is the latest For the Birds column: 

Last week I wrote about winter finches and how birds that aren’t even finches can easily be lumped into that broad category.

I mentioned a few examples and, of course, as soon as I hit the “send” button, an example that I failed to mention showed up in my backyard. It was a fox sparrow. Well, more specifically, two fox sparrows.

Fox sparrows aren’t finches, naturally, they are sparrows, just as their name suggests. But because they are small (relative to all birds) and show up at feeders throughout New England sporadically during certain winters, I think they can be mentioned under the very broad and nonspecific category of winter finches.

Winter finches, just to review quickly, are the northern birds that show up at New England feeders some winters, only to not be seen again for several years. Pine siskin is the prime example and this year seems to be another good year for siskins. Continue reading

For the Birds: Winter finches arrive on the scene

There has been a lot of talk lately about winter finches. There usually is this time of year.

I have read accounts of people seeing big flocks of pine siskins. Siskins are probably the most common winter finch that irrupts into the middle and southern parts of New England sporadically in winter.

Winter finch is not an official term with a clear-cut number of species that nicely fits the category. Rather, it is a general term used for members of the finch family that breed up north and typically spend their winters up north, but irregularly move south during the winter as food sources dictate.

The species most commonly associated with a winter finch irruption include pine siskin, common redpoll and purple finch. Larger finches, such as pine grosbeak and evening grosbeak, are also species seen at backyard feeders throughout New England during the winter.

But birds do not even have to be finches to fall into the loose category of “winter finch.” Often, the red-breasted nuthatch is lumped into the category due to its great abundance at feeders some winters and being a no-show during other winters.

So far this winter I have seen a lone female purple finch at my backyard feeding station. That has been the extent of my winter finch season so far. The nature of a winter finch irruption, however, could mean a sizable flock of pine siskins can show up and empty out my Nyjer seed feeder at any moment.

I did see a few red-breasted nuthatches on a recent trip to northern New Hampshire, but that is part of their breeding and winter grounds, and would not fall into the category of a winter-finch sighting.

Admittedly, it took a minute or two to identify the female purple finch that has been visiting my yard. It was clearly something different, so I knew I had to lock down an ID as soon as possible.

Female purple finches are streaky brown in plumage. It didn’t have the look or feel of a sparrow, so I eliminated those possibilities immediately. It looked a lot like a house finch, but was more heavily streaked and slightly larger and plumper overall. The thick bill further eliminated any sparrow possibilities and after very briefly considering the female rose-breasted grosbeak, I was able to nail down the ID as a female purple finch.

In the past when I have seen purple finches, it has usually been a pair so getting an ID was easier because I had the more colorful male to observe.

For whatever reason, regardless of how great a winter finch season it is throughout New England, my yard typically does not drive in a lot of these birds. While I’ve read about several backyards being ambushed by pine siskins already this season, I haven’t seen a pine siskin in about 10 years. That species typically irrupts every three or four years.

If nothing else shows up at my feeders all winter, I still have my regular feeder birds and my female purple finch. And I’m good with that.

Goldfinches galore

The snow this week brought not only the unexpected visitors, such as fox sparrows, but also the regular visitors such as chickadees, nuthatches, titmice, doves, juncos, and woodpeckers. It also brought goldfinches, which was to be expected, but what was surprising was the number of goldfinches. Every perch on my thistle tube feeder was filled and other goldfinches either waited patiently nearby or “settled” for sunflower seeds at other feeders. There were even goldfinches on the ground among the many juncos.

I hope to post a video of the goldfinches later today. Let’s see if time and my technical knowledge of video programs permit …
