[IBLE] bird vs. bird

The three young Cooper’s Hawk are calling for food. Bkack-capoed Chickadees
are chittering frequently and visiting my tube feeder. Meanwhile, one of
the he Cooper’s Hawks is stealthily moving limb to limb and tree to tree in
my yard. I love Chickadees and don’t want the hawk to win this one.

[IBLE] How Many Hummingbirds?

Every year as I watch hummingbirds visit my feeders I wonder “How many different birds are coming by each day?” Of course, at this time of year this means “I wonder how many Black-chinned Hummingbirds are coming by my feeders each day?” as that is the only species I see during the summer. This year I finally decided to move beyond wondering and see what I could do to actually figure it out.

A little searching on the internet found a few estimation methods. The best way is to do local banding to create an identifiable sample of the birds, but that approach is not available for me. The easiest estimation method is to count the maximum number of birds you see at one time and multiply by 6. This was created by someone who had done local banding and discovered this was a reasonable and simple estimate. In my case I often see 4 birds at once, especially in the sunset feeding frenzy. I once saw 5 but 4 seems like a consistent maximum. So, this would get me to somewhere around 24 different hummingbirds coming by during the day. The other estimation method is based on several people’s studies that hummingbirds drink between 0.25 and 0.50 ounces of sugar water a day (based on the typical 1 part sugar to 4 parts water mix). During the last week, birds have been drinking around 12 to 15 ounces of sugar water a day. This approach results in a range of between 24 and 60 different birds coming by each day – and the numbers will be even higher if they are also visiting other feeders in the neighborhood. And there are many neighbors also with feeders.

Where does that leave me? It seems like based on these estimates that I have at least 24 different Black-chinned hummingbirds visiting each day and it would be plausible for this number to be 30 or even a little more. I find that pretty amazing that this many of them are around. A number which will jump dramatically in a few weeks as the young of the year fledge and join their parents in feeder visits.

[IBLE] Gold Fork Park & Ski Area

Hi birders,
Yesterday Amy Bechtel and I walked the whole trail at Gold Fork (off Hwy 21 near mile marker 59). There is still extensive fire damage following from the 2016 fires in this area, which has created a lot of relatively open areas along the trail. As a result, there is a huge proliferation of wild flowers growing there of many colours and varieties, including geranium species, penstemon, larkspur, mallow, and  Indian paintbrush, to name a few. For birds, it was a good day for woodpecker species, with the burnt areas good for Three-toed and Black-backed woodpeckers. We also had excellent views of a pair of MacGillivray’s Warblers which we watched for several minutes, calling from the low growth along one of the creeks there.
Good birding!John Shortis

Re: [IBLE] Leucistic or Albino Mallard

Albinism would have a complete lack of pigment and color.

This is a domestic mallard variety. It may be a cross between a wild bird and a Kakhi Campbell. It could very well be one that was purchased as a duckling for the kids and then dumped when it grew up and became a nuisance.

Re: [IBLE] Long-billed Curlew Decline in S ID

Thanks Brian for the insights
The poaching threat, as serious as it is for birds on public lands in SW Idaho (People Keep Shooting Long-Billed Curlews in Southwest Idaho), does seem to be relatively localized and I’m sure other issues are at play elsewhere.  And, to your point, some of the best current populations of curlews – both in terms of abundance and reproductive success – we’ve studied in recent years are on private lands with flood irrigation (or at least sub-irrigated meadows), including sites in eastern Idaho and western Wyoming.

As you said, center pivots and other forms of sprinkler irrigation use less water and require less labor.  But, there are other factors worth considering in the “conservation equation”, including impacts on aquifers as well as what kind of habitat these agricultural areas provide.  Flood irrigation, though water & labor-intensive, provides a pretty good substitute for seasonally flooded wetlands and also allows for aquifer recharge.  To that end, many organizations in the state – including members of the Idaho Bird Conservation Partnership – have dedicated energy & effort in recent years to the goal of maintaining flood irrigation in at least some valley areas that are within natural floodplains.  This is especially so in eastern Idaho where White-faced Ibis and other birds that breed at Market Lake and Mud Lake WMAs and feed extensively in nearby flood-irrigated fields … but there’s a very rapid turnover to center pivot in the area which could end up severely reducing important foraging habitat for colonially-nesting waterbirds as well as migratory waterfowl & shorebirds that pass through.
Thanks for chiming in and I hope this adds a little more to your “food for thought” 🙂

Recently, I’ve read sev articles about Long-billed Curlew numbers dropping in S ID & a disturbing reason for the decline. It appears that poaching, specifically “target shooting” is a major factor. The LB Curlew is federally protected by the Migratory Bird Act but that, obviously, doesn’t deter everybody. As unconscionable as “thrill-killing” such a magnificent bird is, I would also like to raise the discussion of, perhaps, another factor playing a role in lower Curlew numbers.

30 years ago in SE ID, LB Curlews were fairly common in most irrigated fields, particularly pastures. But, about a decade ago, I started seeing fewer & fewer. To the point now, at least in my area, Curlews have become rare. I think the switch from flood irrigation to sprinkler irrigation is a factor in the decrease. Certainly, sprinkler irrigation conserves water & is less labor intensive but the flooded fields with standing water have virtually disappeared. And with the disappearance of soaking wet, short grass pasture fields, appears the Curlews have moved on. I’m not advocating a return to flood irrigation, but I believe the change has made a difference. Food for thought. I’d be interested in what others may think.
