More nests.....

The weather couldn't be better!    I love this cool spring, especially on sunny days and it looks like we have at least a couple more in store.   Next week, alas, looks rainy.  But you never can tell.  

I didn't get out yesterday as I was waiting for food deliveries.  But I had bushtits all around my house again and happy little birds they were as I now have a restocked suet feeder.  A pair seems to be hanging out more than the others and I have fond hopes I will have a nest here in the yard.  We'll see!  

I did get out the day before yesterday to Oaks Bottom and made three new discoveries:

1.  I found a nest being built by an unbanded pair in a rose vine on someone's porch very near Sellwood Park. This would be unremarkable except for the fact that this is the 4th year in a row bushtits have built in that very vine.  Last year's nest is still there....looking a bit forlorn, but almost usable.  The even-older nests are gone only because the owner trimmed back the vines last year.  Otherwise, 3 old bushtit nests would be hanging like soggy Xmas ornaments.  

2.  Remember the first year female W-X "rebuilding" at a nest that was built and used last year?  Well, that is happening no longer.  Instead, she and an unbanded male are building in the same tree but about 20' higher.  It's a very early stage nest so we'll see if they stick with it or if someone else takes over.  I did find the pair hanging with another pair near there later in the afternoon, suggesting the second pair in eying the nest site.  

3.  I found a very early stage nest (just a ring of spider web and lichen) along the Bluff trail that, if completed, will be so obvious to anyone on the trail that I am loath to reveal its location.  I find that nests that are that close to the trail often don't do well if people find out about them and stop and watch too much and too closely.  Crows are crafty and learn pretty quickly that bushtit nests are lovely hanging sacks of protein.  Sad for the bushtit families. 

Which brings me to.......

Reed College!   My amazing field assistant, Amelia, who was with me last year, has started searches for nests on campus and so far she has seen banded birds (GYYX and another banded male) with an unbanded female hanging out around an old nest site.  More on that later.......time to go find my birds! 

Bushtits......and the pandemic....

A cheerful flock of bushtits just appeared in the bushes out my front window and made their way around to the back of the house, a bit disappointed that my suet feeders aren't up, I'm guessing.  They are a reminder to me that they are still hanging out in their flocks even as late as 10AM and so are not entirely serious about nesting.....yet.  

But that doesn't mean nests aren't being built.  It doesn't even mean some nests aren't finished already.   It just means no one is incubating yet.  

In all probability these these little flocks (tintinnabulation's, twitters, or whatever we will decide) will break up into subgroups of pairs and contenders for females and nests later in the day as it warms.   That's really what I'm seeing now.  I am rarely running across a single pair building solo.  There always seems to be one or more bushtits hanging out with little chases and even courtship around the nesting areas which are, not surprisingly, about where nests were last year.  

As I watched the flock from the safety of my house, I contemplated what this year's season will look like given the current and future state of the pandemic.  I think (so far) I'm pretty safe heading out by myself and finding nests in the open air.  I have two assistants who (so far) seem ok with that scenario as well.  My plan, as an elder, is to do most of my searching alone to avoid exposure as much as I can.  My two assistants (both in their 20s) can work together if they like as their risk of complications is much lower and and I think they would enjoy the company.  But I'll leave that up to them.  

I think we are all safe watching nests in the field.   That's a solitary endeavor no matter what.  Solitary except for the bushtits, of course. 

The big compromise I think I will have to make this year will be catching and banding birds.  Although I can do that alone, I need help setting up the net and that involves less personal distance than recommended.  Taking blood is even worse because I need to be in very close contact with my assistant.  

And so I am faced with a dilemma:  Do I take the risks I will have to take to continue my study this year?  Or do I stay at home as I have been instructed to and lose this field season and all the interesting information I would get from birds I already know ---- birds that may not be around next year at all ---- to stay as safe as possible.  

I don't know yet.  

But my problems are nothing compared those who are ill or who don't have the luxury of self-isolating.  My heart goes out to all those people who, because we didn't take a strong enough stance on this virus early enough, will suffer and even die.  It is my hope that in the next day or two, Oregon and every other state will close all but essential businesses and "flatten the curve" so that our health care system does not get over-burdened and we weather this very real storm in relative safety.  

Stay well everyone.....and stay tuned.  If I do continue to find and watch nests (at the least) you may find this distracting as you stay home and stay the distance.     

Mar 10-11: Four nests and a puzzle.........already

Yesterday I returned to Oaks Bottom and walked all the way from the southern end to the north and back.  Today I returned to just the southern end and found nests......

This is a quick recap (joined today by a student from PSU);

1.  PPRX is building a nest with an unbanded female very near to his nest in 2018 and right next to the nest he briefly took over last year.  It's also very near where I saw him with the flock on 9 March.  This nest is just a hanging sack so far, on the outer edge of a very large cedar.  Lots of little chases and such with at least one other bird in the area could mean that, on closer inspection, this nest isn't really PPRX's at all. We'll see!!

2.  A young birder extraordinaire (who will remain nameless until I get his permission) found a nest yesterday that is almost finished on the slope about half-way between the southern field and the mortuary building.  Both birds are unbanded (so far).

3.  We found another new and barely there nest hanging over some brambles that had a very successful nest last year.  This new one is being build by an unbanded pair and is just a ring of spider web and lichen.  It's in the lower branches of a giant pine on a slope along the Bluff Trail.

4.  And finally the puzzle....actually TWO puzzles.  W-X (this time a female) and an unbanded male are apparently refurbishing a nest we had last year on the edge of the southern field of Oaks Bottom.  Two things are a puzzle.  First, this is W-X, but not the male I saw with PPRX two days ago.  This is a female.  Now, both of these W-X birds hatched last year in a nest on the edge of this field (dad was PYLX) and are siblings.  The big puzzle is I have never had a first-year female breeding in her natal flock!  They usually disperse out.   So this is "first #1."  "First #2" is really not a first.   It's a "second."  But it's very, very rare.  Only once before have I ever seen a nest reused in another year.   A very rare event!   And the last time (in Arizona) it was also a young first-year pair and not the original owners of the nest.  Interesting.

Last, but not least, I found RXRG (RexRug) with a flock very near his nest from last year.  Also with him was NUNX (Nuns) who was banded as an adult visitor at RXRG's nest last year.  This was all near the juncture of Bluff Trail and Springwater.  I am certain RXRG (who has a very, very complex history which I will detail here soon) has a nest near here.

Stay tuned for more!   I realize that, at this point, it all seems a bit confusing.  But as the season progresses, you will get to know these birds and their nests and shenanigans and be as excited about what they do next as I am.  I think :-)

Day 1: Who and what did I see??

Well today was the first day of the real season for me.  I drove in from Olympia by 2pm and headed out to the southern edge of Oaks Bottom for a quick look at what the bushtits were up to.   I only had an hour, but the weather was so clear and pretty, I couldn't resist.

And what were they doing?  They were messing around in small flocks of 5-10 birds that divided and coalesced seemingly randomly, although I'm certain it wasn't random.  I'll know better when I have more birds banded.

Which deserves a quick explanation:

In Arizona, my study area in the Chiricahua mountains was well within Coronado National Forest and so my study area was, literally, boundless.  The lovely result was that I could be certain I had every bird in a flock (or whatever we'll call it) banded and every nest found.  I didn't have to worry about roads or fences or people's backyards or sensitive wetlands.  I could go anywhere.  Consequently, I could be certain I knew what every single bird was doing from day to day.  Every spring, flocks were full of old friends with just a few new unbanded birds that had dispersed and joined up over the winter or early spring.

Not so in Portland.  The flocks I am finding now are most certainly as cohesive and tight-knit and closely-related as those in Arizona, but I am constrained by the urban-ness of the terrain.  I can never find every nest in a flock because some of these nests are unfindable.  I had one last year that was well out in the wetlands at Oaks Bottom.  Some nests are in backyards.  Others are in areas that are otherwise off-limits.  So I do what I can.  Every year I find as many nests as I can within the constraints of Oaks Bottom, Sellwood Park, Riverfront Park, Westmoreland Park, and Reed campus.  Many of these nests are nests of old friends and I am always delighted to see them.  But every year I have nests with unbanded members of the same flock whose nests the year before I couldn't find.  It is only the observations I make during the breeding season and especially near the beginning and end that verify who belongs to which flock.

I should also mention that every year I see banded birds early in the season and never find their nests!    I know that they are still around when the season starts to end and they show up with fledglings in tow.Very frustrating!

Ok....that's a bit about urban bushtit research!   Not particularly easy, actually.

Back to my short afternoon:   I ran into a conglomeration of bushtits --- perhaps 10 -- near the northern end of the big field.  Most of the birds I saw were unbanded, but I was excited to find PPRX and W-X among them.  W-X is a first year male whose father was PYLX  -- I'm hoping I'll find PYLX who was the "helper" in 2018 at Nest 11 and had his own nest last year.  The same year PYLX was a "helper," PPRX had a nest very close by that was successful twice.  So PYLX and PPRX are clearly members of the same flock...perhaps even related.

Now PPRX is a male who has been a very successful breeding male for the last two years and he is a real character!  Last year he booted PYLX out of his first nest after finishing a clutch of his own at another nest and leaving the female to incubate alone (a no-no and the same thing LLRX seems to be capable of).  Then he himself gave up on PYLX's nest (never knew why --- someone  else eventually rehabbed it and moved in) and became the doting father at his original nest where he and the female raised two broods successfully.

Poor PYLX, in the meantime, seemed a bit lost although he continued to hang out in the area.  He finally nested late in the season in a small tree at the opposite end of the big field and successfully raised a brood of four -- W-X was one of them.

So....not much to report yet, but two banded birds in just an hour and verification that nest-building is imminent based on the loose nature of the flocks and some chases I saw, was better than nothing and a nice start to the year!  I'm sure there are already nests out there just waiting to be found :-).  And more of my banded friends.

What to call a flock of bushtits?

While I await my return to Portland (I'm in Olympia with friends) I think I'll post a very interesting thread from OBOL.  We are all familiar with various names for flocks of other species:  a gaggle of geese, a murder of crows, etc.   But, as far as I know, there is no "official" name for a flock of bushtits.  Perhaps we can rectify that with a contest.

It started with a query:  What do you call a flock of bushtits?  And there was a cascade of responses from OBOL list serve members.  I expect more will come.

I'll list the suggestions people have emailed on OBOL and then we can take a vote.  I'm open-minded!    I'll keep names off the list, but include explanations if needed.  When there is a consensus (that would be nice) or a majority in favor of one, I'll declare the winner and that is what will go into my book.  I suggest "Ranked-choice voting:"  Choose your top 5 favorites and rank them in order of preference.

Here we go.   If you'd like me to post your name with your suggestion, just let me know.  Some are silly, but most have some interesting descriptive character.

1.  Psaltriparus minimus glosses as 'smallest harper-tit.'  A collection of harpers is a melody.  The smallest significant part of a melody--beyond a note--is a motif.  QED: a Motif of Bushtits.

2. Swarm of bushtits

Back in Portland....

......and the field season begins!

From now on, on good weather days when I can get out in the field, I'll be reporting what I see scattered with tidbits and details about the relevant behaviors.   My hope will be that blog readers will become as attached and interested by what goes on with the bushtits in Portland as I am.

Nests are being built, I am certain, so keep your eyes peeled for bushtits carrying nesting material --- especially big blobs of spiderweb.  Or their large hanging nests.

This one was right on Reed campus 2018 near a dorm and was very cryptic.  The parents were AXAA (Captain America) and FFFX (F-X).  One of the female juveniles showed a great deal of interest in the second nest for quite a while before they fledged, but never helped feeding.  Right before it fledged, some unknown predator ripped the bottom out of the nest, but not deep enough to get to the kids and all was fine!!   I couldn't find the nest of AXAA and FFFX last year although I looked.   I know they were still around because they visited the Reed suet feeder.  Ah well!!
