Birds captured: 15 individuals of 9 species

  • 1 Black-throated gray warbler
  • 2 Bewicks wren (2 HY)
  • 1 Purple Finch (AHY/F)
  • 1 Hutton's Vireo (HY)
  • 2 Western Tanager (2 HY)
  • 2 BH grosbeak (1 HY, 1 AHY/F)
  • 4 Spotted Towhee (all HY)
  • 2 CA towhee (2 HY)

 

Hi all, things have certainly quieted at the BCCER with no detections of Orange-crowned warblers, Yellow-breasted chats or Lazuli buntings.  We had several young towhees and a Bewick's wren in full juvenile plumage and molting Black-headed grosbeak and western tanager young.  A nice surprise was a female black-throated gray warbler, an adult (AHY) in full blown prebasic molt.  I've attached a picture so you can see some of molt characteristics of an AHY.  You can see fresh (dark and clean) vs old (faded and worn) primary feathers with associated privmary coverts, something you would not see in most (exceptions are always out there!) HY birds who would retain all flight feathers and primary coverts until next fall - only molting secondary coverts at this time. She was also in heavy body molt.  whew- lots of energy expenditure in this girl!

We had an interesting day with singing chats- never detected in this area, except for 1 hatch year that we captured last year.  We are upslope from Big Chico creek and in heavy brush (an old burn site) which had become more dense over the last two years.  We captured 3 adults, including a breeding pair- see pics, the female on the left with grayer lores (area between eye and beak) and lighter bill. Lots of baby Orange-crown warblers today: see picture of 1) baby face-notice yellow gape and short bill, and 2) undertail coverts with young on left vs adult on right.  The new juvenile feathers are loosely textured with not much structure, while the adults are well-formed.  We also had 2 second-year male purple finches.  Unlike the house finch, this species goes through a second molt before it develops the beautiful purplely plumage, but these two showed some new colorful feathers (see pic) and also were in breeding condition. We had one second-year Swainson's thrush, loaded with fat for migration (see pic).  The fat is bulging over the furculum (wishbone) and is yellowish under the skin (see pic).

Birds captured: 15 individuals of 10 species

  • Dusky flycatcher (dorsal view)
  • 1 Lincoln's sparrow
  • 2 wrentit (breeders)
  • 1 MacGillivray's warbler (SY-male, see pic)
  • 2 Hermit thrush (1 recap from March 2006-at least 4 years old!)
  • 4 golden-crowned sparrow (1 recap at least 4 years)
  • 1 CA towhee(breeder and recap at least 4 years!)
  • 2 Bushtit (both recaps-breeders)
  • 1 Lazuli bunting (recap from June 2006- at least in 4th year: at same site!!!)
We had a fun day on the BCCER, first noting migrants that we detected setting up nets: our first of spring (FOS)Lazuli bunting, MacGllivrays warbler (FOS),and then migrants ash-throated flycatcher, Bullock's oriole, western tanageer, warbling, Cassin's and Hutton's vireo, Blue-gray gnatcatcher, Hammond's flycatcher, Orange-crowns (only 1 singer- they are likely nesting now).  Happily, following our auditory detections, we captured 2 of these (!) plus an undetected Dusky flycatcher (see pic). I think our captures of most Hermit thrushes and GC sparrows now are those moving through- not necessarily those that have resided here during the winter.
 
I had  conflicting plumage characters with our Lazuli bunting.  Younger birds have more brown-tipped body feathers, as did ours, but older birds have fresher, more square-shaped feathers,as did ours.  This recap male had lots of brown body plumage, but adult flight feathers, so, we aged it as an after-hatch year.  This is the safety-net age, we know it is too early to be hatched this year, but could be older than 2 years.  Retrieveing records, we found our boy was first captured in June 2006 as a second year male - making him at least 4 years old - AND, coming back to the same site.  How cool is that!? Our Dusky flycatcher was also a challenge-see pic.  We made at least 20 measures to determine this species, knowing it was different than our Hammond's  2 weeks ago, despite Hammond's being the only singing empidonax detected this morning.  A great day for us!

Hi All, a beautiful day at Toyon Slope albeit somewhat quiet.  Mike Skram conducted point counts and neither of us detected any FOS migrants.  I did not see one fruit on any shrubs (the presence of fruits is why I think Toyon Slope is a boom-or bust) but many are beginning to bud (snowberry,buckeye).  We captured two beautiful Purple finches with obvious plumage color differences between males (see all pics).  Although both are after second year (ASY-- over 2 years of age), one had more red wash to both upper and underparts. "Reds" were of a different hue with one being more raspberry (bird on left), the other a purply orange (bird on right).  This may be due to diet differences that is known to result in plumage color differences in house finches.  Other highlights were several overhead flocks of snow geese mixed with white-fronteds and sandhill cranes.  We had our first newts of the season and lots of water in springs on site.

  • 1 Hermit Thrush ( recap from 2005, bird is at least 4 years old, see pic)
We had a beautifully warm winter day at the BCCER.  Our morning started with a mixed flock of white-fronted and snow geese, followed by tundra swans, all glowing against the blue sky.  We flushed a flock of ~50 band-tailed pigeons on the reserve. Most all fruits are off the toyon, so activity was somewhat low around the nets.  Instead, large flocks of robins were foraging mistletoe fruits up in the canopy.  Our most common winter species, Hermit thrush, was notably missing from nets (only one capture), and I don't recall hearing them in the field. We've had this species well into April, so likely it was just a poor netting day for hermits, or as Colleen Martin said, "a good day for a hermit thrush if you're a thrush."   Milkmaids (Cardamine californica) are already in bloom!      Photos by Steve King.

All, after our fantastic banding workshop, 6 students got to practice their skills this weekend.  We banded at BCCER and all had an in-hand lifer, the Red-naped sapsucker that the Kings had photographed several weeks earlier and had been hanging around in the same oak tree.  I was the lucky one having approached Net 8 ( a net that is not typically productive) and saw 4 birds- including a flapping and ready to escape Steller's Jay. As I ran toward the jay I passed one hermit thrush and two sapsuckers and thought, hmm, that one sure has a patterned face...  In the net was the jay and hermit thrush, a red-breasted, and red-naped sapsucker; Jackpot!  Both days were busier in the late morning as the temperature increased from near freezing to mid-60's. We had grand flocks of band-tails (BCCER), Snows and WF geese, Tundra Swans, and Waxwings (BCEP) in the area and overhead. Point counts were conducted on both days by Brad Stovall (BCCER) and Mike Skram (BCEP).  Mike thought he saw a western tanager and- we caught one, a very gray female.

First Summer day banding in Chico. A quiet day, both banding and point counts, at this site for migration- but, great to be out. A black bear ran from our site on our arrival, likely after the very ripe coffeeberries. Also snowberry and CA grape ripening. Thanks for the photos Scott! Here are the results:

It was a lovely day for migrants and summer breeders.  While putting up nets I had a nice male Black-chinned hummer come and check me out and MikeSkram had a female- maybe collecting nesting material at the creek.  He also had an Olive-sided flycatcher. Both not rare, but 2 new documented species onsite (by me).  Still in the canopy lots of netrop breeders but many migrants are moving on and out.  We had a good net day with our first two captures, the ever elusive skulker- Swainson's thrush!  Here are the results of our great day.

D. Garcia,

Migration continues at the BCCER!  Yesterday I had lovely color and song in the oak canopy with several small foraging flocks and individuals of Western Tanager, black-headed grosbeak and Bullock's oriole. Also Townsend's (gorgeous male!), Yellow-rumped, Orange-crowned, MacG, and black-throated gray warblers.  I heard Nashville singing.  Haven't had any LazB's yet (except for the one we saw on our big day April 13), and have yet to detect a chat although Mike Skram had one a week or so ago a the BCEP.   The nets were slow compared to the medley above, but I still had some nice surprises.  Here are the results.  Can someone ID the caterpillar I saw?-blue sides and rust-colored tufts.

Birds captured: 11 individuals of 9 species

  • 3 SPTO (spotted towhee-1 recap)
  • 1 OCWA (orange-crowned warbler)
  • 1 MGWA (MacGillvray's Warbler) (2nd pic)

We set up nets at the BCCER after a short storm and a few showers.  The morning was rather slow although we had a new migrant- an empidonax flycatcher that I was uncomfortable identifying to species.  I've included photos (back, head, mandible) for y'all to take your best shot.  Also new in the net were wrentits.  It was the first day I had heard them at the site although I have heard them on the reserve before. 

Birds: 17 individuals of 8 species

  • 1 flycatcher (p6 emarginated) [Willow Flycatcher]
  • 2 Lesser Goldfinch LEGO (1 recap)
  • 2 Wrentit WREN
  • 2 Bewick's Wren BEWR
  • 2 Western Tanager WETA
  • 1 Downey Woodpecker DOWO
  • 6 Spotted Towhee SPTO (all juvs)
  • 1 Anna's Hummingbird ANHU

Hey everybody, thanks for the input on the BCCER empidonax.  After reviewing your comments, my photos and measures,-I ID'd this bird as a Willow Flycatcher (as did most of you although gray and dusky were discussed.)  What really helped was an excellent banding day (115 birds!) at Jim Steele's site in the Carman Valley, eastern Sierras where we had an excellent mix of empidonax- WIFL, dusky, gray, Hammond's and several peewees thrown in.  I've attached a couple of comparison photos and feel much more confident with my empidonax ID./p>

Hi all, following are the results for bird-banding at the BCCER.  It was a day loaded with juvies in the nets; only 9 (39%) of our 23 captures were adults. Mike Skram also conducted point counts.  We noticed that the morning was rather quiet with many fewer singers than on previous counts. Only warblers heard singing; yellow-breasted chat and black-throated gray (see pic of juv).  Our Orange-crowned recap was in heavy molt (see pic-shows 3 retained old secondary flight feathers, contrasting with newly replaced and growing in {97-p9} feathers.  Head and body also full of feathers "in pin."  With all that energy sustaining feather replacement- it is no wonder we don't hear these birds singing now!

We had a good day to take a snapshot of breeders at the BCCER at our Toyon Slope banding site. I expected more young but we only captured one-just out of the nest spotted towhee.  Most other captures had breeding characters; brood patches (BP) or cloacal protruberances (CP).  New in the net and hand for all of us were three Ash-throated flycatchers.  We could not determine the sex on these birds as males "may exhibit a poorly developed CP" and both sexes develop BP's-although the females would be more developed during the peak incubation period.  We had nothing on the trio-but could determine age.  In the SY- the primary coverts (feathers above and associated with the primary feathers) are retained, worn and faded, whereas the ASY bird has replaced these so feathers are uniform in quality, and general color and appearance (see pic SY-ASY).

Today was our final formal day of migration monitoring- most migrants have arrived- just waiting for the cuckoos!  We had a great crew of people and Mike Skram ran point counts.  He had 2 pairs of blue-gray gnatcatchers displaying and also heard yellow- breasted chats, newly detected on the site, along the creek.  New in the nets was a house wren and a beautiful male Bullock's oriole (see photos).  I plan to monitor at least once a month (every 3rd Saturday) until fall migration. Following are the results of the day.

Hi all, just about to finish up spring migration monitoring with a couple of more banding sessions.  Friday we set up at my first site-down near the creek. We had several singing yellow warblers, Nashville warbler, orange-crowned, and black-throated gray warbler-pacific-slope flycatcher and western wood peewee-many tanagers, bullock's oriole, Hutton's and Cassin's vireo, and laz bunting.  Mostly they stayed high and avoided the nets but on our first round we had 4 beautiful western tanagers. Two new detections for  the site were a Lawrence's goldfinch seen by Randall and Brad conducted point counts and picked up phainapepla.  Following are Friday's results.

Hi all, following are the banding results for the BCCER.  We had a nice morning with three new bird species in the net for the site- a Lazuli bunting (LAZB-see pic), Bullock's Oriole (BUOR-see pic), and Swainson's thrush (SWTH).  Mid-morning I heard a new song and looked up~40' in an oak at the very top- and said "look- a lazuli!"  We all danced around at that, with the comment that he was a little high in the canopy to land in the nets.  On the next net run~ 10 minutes later- we had a bright young male lazuli in the net just under the oak!

An unrelated sighting- I had a Western Wood peewee singing along the south fork of the American River yesterday (May 6)-the first I have heard this season.

Excellent day with migrants moving through and some resident birds captured too. Surprisingly, only a male orange-crowned warbler (OCWA) had the first cloacal protuberance (CP-a swollen cloaca that males develop in breeding season) of the season, despite having captured Bewick's wren and spotted towhee, both resident birds with no breeding characters. New bird in the hand for me was a handsome white-breasted nuthatch (see attached) - a sparrow sized bird!  I am much more accustomed to the petite red-breasted nuthatch-warbler sized.All three GCSP were undergoing prealternate molt.Julie and I started avian influneza sampling (cloacal swab).Julie uncovered a young gopher snake (see attached pic) we saw many newts, and I saw a western skink later in the day. Lots of new blooms  including Sierra fawn lily.

Results of the second banding effort at the BCCER migration station.  It was the day of the Ruby-crowned kinglet (RCKI).  No yellow-rumps were detected until after nets were closed and then I only saw/heard one chipping.  Only other warbler singing was Orange-crowned (we banded our first today for this station).  I expect to begin seeing some breeding characteristics (brood patch/cloacal protuberance) on the residents but have not to this date.

Birds captured: 18 individuals of 8 species

  • 1 Bushtit BUSH (recap male)
  • 7 Ruby-crowned Kinglet RCKI (all males)
  • 1 Oarnge-crowned Warbler OCWA
  • 1 Oregon Junco ORJU
  • 4 Hermit Thrush HETH (2 recap from March 23, 2006)
  • 1 Golden-crowned Sparrow GCSP
  • 1 Fox Sparrow FOSP
  • 2 Spotted Towhee SPTO

Some great flowers out!  Scarlet Fritillary (Fritillaria recurva); Yellow Star-tulip (Calochortus monophyllus )

Great day for newts too- counted 35 in a very small area near the Creek.

As most of you know it was a cold and blustery day-which did not bode well for mist-netting, the wind billows the nets like sails making them visible and avoidable to birds.

Jackson and Mela arrived with Jeff Mott and crew of ~18 people.  We split the group and Jackson and crew went down the road for some chilly birding.  The first banding group entirely missed any netted birds but we made a few forays off of the net loop.  First we visited the enhanced frog pond created by Dr. Paul Maslin and Jeff Mott and saw tiny metamorphosing tree frogs in giant gumball-sized egg masses. After another empty run, Mike Fisher took the group on a short bird walk while Julie Nelson and I went on to check nets.  Jackson came back with group 2 and we all tried to warm up under the ! shelter of the barn. Happily, on our next run we caught our first two birds.  On the next net round we caught four more birds. Then it began to rain. We closed all nets, processed our birds, packed up and ended our trip.  A rather uneventful day really, but everyone had the opportunity to observe the banding process.  Several budding junior birders and some adults too, got to touch and release their very first bird in the hand.

 

Birds captured: 6individuals of 2 species

  • 2 Lesser goldfinch (HY/F)
  • 4 Spotted Towhees* (all male).  Curiously, the last 11 spotted towhees captured in this area since Jan 15, have all been male!

*after second year (ASY) male- note deep red eye and dark black, glossy plumage. As you would expect, towhees have long nails for scratching and kicking through plant litter for food.

These casual attempts were primarily to identify birdy net lanes for the upcoming snow goose festival banding demonstration this saturday.  What we found was the site continues to be less birdy!, as water is more available in seeps and pools and starthistle and fruit bearing trees/shrub continue to senesce. We also attempted an owl night at the off site property in forest ranch; nothing!  My excitement is a slate-colored junco that has been hanging around my house-(see attached photo).

Birds captured:8 of 5 species

A beautiful but pretty slow day and not as birdy in the past in this location.  Could be attributed to lack of fruit on the fruit trees, starthistle almost spent (not many LEGO around), abundance of water in the area (no dependence on water trough where WEBL and LEGO were regular) and cold temps.One person was confident they heard a NSWO- otherwise no-one heard any owls.  We also tried for NOPO with no response. Hypothesized that heavy rains at this elevation (3,000' msl) may have driven owls to valley??

Birds banded: 11 of 5 species

We set up only 2 nets at the barn (AKA COuntry  CLub-due to its cushy amentities), #1 near the water trough and barn and #2 near a pair of pomegranate trees.  We made 3 net runs and closed the nets due to a fair number of birds and new volunteers. A good training session and lovely day with lovely birds.  In addition, Mike Fisher and I saw a perched golden eagle on the way up, a likely bald eagle, and an unfortunate gray fox-hit by a car.

We noted that the birds had moved upslope from most of our nets with the fruiting toyon.  We caught more leaves than birds and likely had 3 towhee escapes due to taut nets and wind.

I set up to take advantage of the lull before the storm and played NOPO calls early in the evening and the 3 netted passerines (towhee and thrushes), must have come in to mob it.

following are the results of the bird banding for October 23, 2005. We opened our new site "Toyon slope", named for its' dominant community of Toyon mixed with snowberry and coffeeberry, in an old burn.  There is an overstory of oak and plenty of snags and debris piles. Grasses, starthistle, and wild grape make up the ground cover.  Knowing the place was birdy we only erected 4 nets, figuring that would keep us busy for the morning.  Indeed it did; after only 1.75 hours we closed the nets due to our large bird capture-14 in one net and 19 total on our second net run-we closed for the morning to process birds and get everyone off safely. The photo shows 2 awesome volunteers, 14 bagged birds and the banding site in the background

Birds banded: 24 individuals of 7 species

  • 8 BUSH- Bushtit
  • 3 RCKI- Ruby-Crowned KInglet
  • 1 HUVI- HUtton's VIreo
  • 5 HETH-HErmit THrush
