    Blue Jay Call

    Sounds to me like a variation on what Donald Kroodsma refers to as the “pump handle” type of blue jay call, one of the five types of blue jay calls categorized by Kroodsma. There’s a good YouTube video series in several parts describing the variety in blue jay calls and sounds.

    Zeiss Dialyt 10x40 B T * price

    Greetings. I still use the 10x40 BGAT/P Dialyt binocular I bought new in 1992, and mine are also in excellent condition. I have not used or handled current alpha binoculars, so I can’t tell you how they compare or their relative value. I can only say I believe the market value of my Dialyts has...

    USFWS Barred Owl Removal Plan

    That's a reasonable question, and I would guess that question could, in a scientist's or policy analyst's mind, be asked in a slightly different way: what ecological role was played by the spotted owl in the northern Pacific that caused it to appear and live in that habitat without any incursion...

    USFWS Barred Owl Removal Plan

    As an employee of a large government organization, I feel compelled to offer a feeble defense of the Fish & Wildlife Service against the suggestion that it is deviating from its original mission with counterproductive results. The history of that particular organization (for which I confess I’ve...

    USFWS Barred Owl Removal Plan

    I was actually talking about the loss of the species from that ecosystem. While it is certainly also about the loss of a subspecies of the total species population in the USA, as you know there aren’t a lot of spotted owls elsewhere in the USA. I was lucky to see one of them roosting over a...

    USFWS Barred Owl Removal Plan

    I want to make clear up front that I have no idea what the proper solution to spotted owl population reductions should be, and I have no idea whether the proposed barred owl removal plan by the government is justified or the best solution to the problem. However, it seems that there are a few...

    Quick question…. Useful camera settings for Sony zoom ?

    I shoot at four frames/second. I use windows photo and explorer, with the Microsoft raw image viewing extension, to preview all my images from the shoot. I select the images I want to save and process, then I use the free GIMP program to process and export them. GIMP does all I need with my...

    Sony RX10 1V the new boy.

    I've only begun to use this camera, but I have found that flexible spot AF with focus lock works well (in most cases) to isolate and focus on a small bird with foliage or branches around it, as others have suggested here. I have programmed my camera to use this for perched birds, and the focus...

    Sony RX10 1V the new boy.

    I have Steve’s book. It’s helpful for those of us who focus on animal and nature photography - especially birds. However, for the general camera user and those completely unfamiliar with the camera, it isn’t as comprehensive as Alexander’s book. And as helpful as Steve’s book is for bird...

    Sony RX10 1V the new boy.

    OK, I returned the first RX10 M4 due to the speck of dust on the sensor showing up on images. I ordered a second camera, but didn't even get to unboxing it - had to refuse the shipment, as the shipping company pummeled the outer and inner boxes to the extent that I felt I had to refuse the...

    cape may in late September?

    Yes, late September is a good time generally for birds at Cape May. You will find passerines at Higbee Beach (dunes and woods) around sunrise and just after sunrise. Also check the South Cape May Meadows for shorebirds and waterfowl. At Cape May Point, falcon migration usually peaks between...

    Arizona birding

    I've only been to southeast AZ during early May, and I'm no expert. According to reports of others, you'll get more migrating passerines in late August, but in October you'd have some wintering ducks and raptors. Also, in October, some residents will be at lower elevations than they'd be at in...

    Sony RX10 1V the new boy.

    Oh, that's a shame. I'm sorry to hear that you, too, were a victim of poor quality control. This worries me about getting a replacement, but I will probably do that, as no other camera can do what this one can do - when it works as it should.

    Sony RX10 1V the new boy.

    Thanks, Malcolm. I think your suggestion of returning the camera to the retailer is the right way to go. The repairs would actually be done by a shop in Connecticut. The return is easier, except that I’ll then have to put a screen protector on the replacement and re-program it. I hope you’re...

    Sony RX10 1V the new boy.

    What should I do? On my third outing trying out my new RX10 IV, I took some photos of an osprey that included large patches of sky - and found to my disappointment that there is dust or dirt on the sensor that is showing up on the photos. I called Sony, and they agree with my assessment. They...

    Sony RX10 1V the new boy.

    I finally received my RX10 IV, and took it out for a trial run on Sunday. I am very impressed. It is already obvious to me, after just a few hours of use, that this camera will allow me to get shots I could never get with the old technology I was using before. I think it paid off to study...

    Sony RX10 1V the new boy.

    Photo Editing Option: In anticipation of buying a RX10 iv, (after slogging along with my old Canon SX10 for 15 years), I just discovered the wonderful free photo processing program called GIMP. It only took me about an hour to learn all I need to know about using it to do sharpening, size...

    Why people should not sort their trash

    The answers to the questions you asked should include an accounting of the future benefits of today's work, should it not? The fact that we are being asked to spend more time now attending to recycling and other environmental work does not mean that it costs us more in the long run. The...

    Olympus LS-P4 / ME66-K6 "wind-like noise"

    I use the LS-P4 with a ME66/K6. I don't believe the mic zoom and mic select settings make any difference when you have the ME66/K6 plugged into the recorder. Those settings are automatically ignored by the recorder with an external mic plugged in. I record in PCM mode, as you do. I find that...

    ME66 windscreen, K6 roll-off filter

    K6 Roll-off Filter, Windscreen I bought a Movo Photo WS220 windscreen, as an inexpensive alternative to a Rhode or something else more costly. I have not had an opportunity to test it yet on my ME66/K6, but I think it will be an improvement over the foam-only windscreen I was using previously...
