FAQ

How do I return or exchange items?

Return & Exchange Policy

If you are unsatisfied with your purchase or ordered the wrong item, please contact us via email (avinet@briloon.org) and we will gladly accept it back for credit, refund, or exchange within six months of purchase, under these conditions:

1. If you paid by credit card, within 60 days of your purchase date we will issue a credit to the credit card that originally paid for the item.  We will do this after we inspect the item and determine that it's in re-sellable-as-new condition.

2. If you paid your original invoice by check, money order, ACH, or wire, or if the item was purchased 
under a Purchase Order, we will issue an exchange or refund, or credit your account, only after inspecting 
the item and determining that it’s in re-sellable-as-new condition. 

3. Shipping (and sales tax in ME) will be added if we send out a replacement item for you.

4. Unfortunately, there is a lot of work involved in receiving returns. We have 
determined that we must reduce any refund by 8.5% to cover the costs of processing a return.  To repeat, 8.5% 
will be deducted from your refund if you ordered the wrong item or just changed your mind.

5. Whenever possible, please provide us with the invoice number or customer number of the original order.  One way or another, we must find the original invoice before we can process a return for you.

Of course, if an item is defective in any way, the 8.5% deduction from your refund will not apply.  Because different products are treated differently, please call our toll-free number to discuss any faulty items.   We ask that you help us to improve our service to you and your colleagues by providing as much detail as possible about what went wrong.  Thank you.

Many returns are due to ordering the wrong size leg bands, nets, or other items.  If in doubt about what size to order, please see the FAQ section, consult a colleague, or email your question to us.

Special note on mist nets:  surprisingly, most of the nets returned to us for holes in the netting or broken trammel lines are found to have been nibbled on by rodents.  If we determine that a returned net has been the victim of rodent or other animal damage, we will ask for your authorization to bill you for any significant repairs before returning the nets to you.  Please keep this in mind and take care to rodent-proof your net storage area. 

 

What’s the difference between nylon and polyester?

It depends on the climate of your mist netting site. Polyester is a little bit softer and has less elasticity than nylon, and performs better in wet and humid climates. Nylon can be just as durable as polyester, but performs better in regards to maintaining tension in dry, well-aerated sites. Overall, there are no long term studies that we have conducted examining durability of polyester and nylon nets side by side, and every researcher seems to have a different preference of material. If you have questions about your particular site, please feel free to consult us for advice. 

Where can I learn about bird banding?
What mesh size should I use?

Here's what Bill Hilton, Jr. has to say about mesh size:

25mm (1") x 50/2
This is the smallest standard mesh size, usually used only for 
hummingbirds. Some banders prefer this size for capturing 
kinglets and the smallest wood warblers, but birds even as 
small as Song Sparrows will sometimes bounce out of this 
net; species that take sizes larger than 0 or OA are best 
captured with a larger size mesh.

30mm x 70/2
1-1/4" x 50/2
This net works well at capturing typical wood warblers, 
wrens, smaller sparrows (Chipping, Field, etc.). Loosely set, 
it will capture birds as large as Northern Cardinals, but it 
works best for birds that take sizes 0 and 1.

38mm x 50/2 & 70/2
1-1/2" x 50/2
36mm and 38mm mesh is the "all-purpose" size for banders 
who can't afford to purchase several different mesh sizes. 
Although hummingbird, chickadees, and kinglets may slip 
through this mesh, with enough bag it will usually catch  wood 
warblers and sparrows, plus most birds that take 1A or 1B 
band sizes.

60mm (~2-1/2") x 110/2
This net is ideal for jays, all but the smallest woodpeckers, 
mourning doves, robins, grackles, etc. Birds the size of 
chickadees and wood warblers can slip through almost without 
stopping. In general, this size works well with birds that wear 
band sizes 2 through 5.

My pole sections don't fit together anymore.

The problem is probably a connector that got mushroomed from frequent pounding in hard ground.  Use a file to remove the mushroom. Scroll down to next Q/A to see an old pole that has been filed. 

We recently changed from color anodizng to hard anodizing the connectors. This makes them much harder and should significantly reduce mushrooming.

The open end may have been bashed out-of-round. First be sure that out-of-roundness is really the cause. If it is, cut off the bad portion with a hacksaw, and deburr the opening. Start by removing an inch of tubing, repeat if necessary.

Note: Pounding poles with a hammer will mushroom the connectors sooner than using a pole pounder.  Pounding with a pole pounder will reduce, but not eliminate mushrooming. Pole pounders are handy if you must hike long distances to your banding site/s. If the substrate at your sites is soft, you may never notice any mushrooming.  A two pound hard rubber mallet will be kindest to pole connectors but it may not provide enough impact in hard gound, it also won't be so convenient to carry long distances. When pounding poles into hard soils, instead of the connectors mushrooming, the mallet will probably start to fall apart. 

The pole points are now hard anodized as well. The point angle has been increased and they are now blunter at the tip. These improvements should eliminate the tip of the points bending over when pounding into very rocky substrates. -s-

How do I keep the loops up?

Angle your poles slightly out at the top to provide tension. Use a hitch in the loop. The ridge formed by the connector will provide a sure grip for the top loop.

What kind of permit do I need to purchase color bands or blood sampling supplies?

For color bands, we require a federal or state-issued permit allowing placement of auxiliary markers or bands on migratory birds. It usually reads as the following on BBL permits:

We make exceptions for captive or rehabilitated birds. If available, please send us your rehabber's permit.

For blood sampling supplies, we are currently only able to sell them within the USA because of importation laws. We require your permit to specifically list your authorization to take, possess, and transport blood samples, and we cannot make exceptions. 

Please contact us if you have any questions about what is appropriate permit documentation.

How can I seal (weld) plastic bands?

I haven't tried one of these but it should work.

ISO-TIP cordless soldering iron

A bander reports that Circuit Specialists shipped his cordless 
soldering iron order promptly.  More on technique later, when I 
hear from experienced Darvic welders.

How should I decontaminate a mist net to help prevent the spread of white-nose syndrome in bats?

As white-nose syndrome spreads rapidly across the US, it is very important for all bat researchers to use proper decontamination procedures to help prevent the spread of the deadly fungus. Mist nets in particular need to have special care taken in the decontamination procedure to make sure they are properly treated. US Fish & Wildlife Service on behalf of www.whitenosesyndrome.org recommends submerging mist nets in hot water (≥131°F or 55°C) for 20 minutes taking great care to not let the water boil. Boiling a mist net is the best way to ruin it. Please visit https://www.whitenosesyndrome.org/resource/united-states-national-white-... and download the full PDF document.

Where can I get a band color sequence generator?
What are your special UV resistant rubber bands used for?

For trammels to all have the same tension they need to be the same length.  Also the net poles need to be perfectly parallel to each other.  If both conditions are not met, some trammels will sag.  After long use even the trammels on our USA made nets will stretch, leaving some longer than others, depending on how you use them.  Inexpensive nets may start out with some trammels a little longer than others.  Banders may have difficulty setting their poles perpendicular to the ground. 
So banders have employed a number of remedies to compensate.  Some use ordinary rubber bands which deteriorate rapidly in days when exposed to UV light.  Other banders cut rubber bands from inner tubes which last longer but are a hassle to make.  We decided to have some custom made for your convenience. Simply loop the bands through existing loops on short trammels ends and over the poles.  If you need more compensation range, use rubber bands on both ends of your trammels.  If you are using USA nets you can attach the bands directly to the plastic trammel rings.

What’s the difference between celluloid and Darvic color bands?

The big advantage of celluloid bands is the ease with which you can seal them (with acetone). They also hold their “memory” a bit better than Darvic. Unfortunately, the sheet material required to make celluloid bands has been exhausted, and one by one, the celluloid colors are becoming unavailable. We will continue to order as many celluloid bands as we can, for as long as we can. 

Darvic is the trade name for un-plasticized PVC, which is dyed with colorfast dyes and is UV resistant. That’s the number one advantage of Darvic bands. It is possible to seal Darvic bands with plumber's UPVC Solvent Cement, which uses methyl ethyl ketone as a solvent to partially dissolve the plastic to form >a bond. Acetone will not work on Darvic bands and Superglue (tm) is unsuitable because it does not work by solvent action1. For the strongest bond, you may melt the seam of the Darvic band shut, using a small portable soldering iron. (Thanks to Nils Warnock of PRBO for his guidance with Darvic band issues).

Important note: Store leg bands at or under 110°F (43°C) or bands will lose curvature and break, and we do not recommend storage in plastic, both long and short term. Do not leave leg bands in your hot vehicle or a hot metal boat!
